illiam Crockett Cooley,rocket scientist, mechanical

engineer, founding member of theWaterJet Technology Association(WJTA), and WJTA Pioneer Awardwinner, died in Anaheim, California, onOctober 27, 2006, after a long strugglewith Alzheimer’s disease. He was 81.

Dr. Cooley was born in Lakeland,Florida, in 1924 and raised in RandolphCenter, Vermont. He graduated fromGreen Mountain College before joiningthe Navy V12 Program at theMassachusetts Institute of Technology(MIT), where he received aBaccalaureate degree in mechanicalengineering in 1944. He then earned aMaster’s degree in aeronautics fromthe California Institute of Technologyin 1947. He went on to receive adoctorate (ScD) in mechanicalengineering from MIT in 1951. Dr.Cooley was a pioneer in jet propulsiontechnology. His career spanned 45years from his early years as a rocketscientist with the Navy, NorthAmerican Aviation in Los Angeles, andFairchild Engine and Airplane Co., Ltd.He also worked at General Electric inCincinnati as a nuclear propulsionengineer. In 1959, he joined NASA,where he became chief of the spacepropulsion and auxiliary powerprogram. Dr. Cooley was a long-timeresident of the Washington DC area.

In 1963 he left NASA to becometechnical director of an engineeringfirm, Exotech, Inc., where he servedas project manager for thedevelopment of the first repetitive-firing water cannon in the U.S. Hethen founded his own engineeringconsulting firm, Terraspace, inRockville, Maryland, which he directedfrom 1968-1984.

At Terraspace he directed researchin hydraulic mining technology; thedesign of a jet cutting system forgranite; correlation of data on liquidcutting of rock and other materials;fabrication and testing of a watercannon for rock cutting and hydraulicbursting for the excavation of rock andconcrete. During this time, Dr. Cooleywas a pioneer in acquainting theWestern world with the advances in

waterjet technology achieved in theformer Soviet Union. He wasinstrumental in translating manyRussian books, and he published asummary of their basic findings.

Dr. Cooley worked as an associateprofessor of computer science andengineering at George MasonUniversity in Fairfax, Virginia,from 1985-1991. He was active inthe Learning In RetirementInstitute where he served as a boardmember, studied, and taught. Healso tutored high school students asa volunteer. A lifelong skier,Dr. Cooley won awards fromNASTAR when competing as asenior. He enjoyed playing tennis,ballroom dancing, swimming, and,in his later years, wrote poetry.

KMT Acquires Two American Companies

K


MT has acquired RoboticProduction Technology

(RPT), a leading robotic trimmingsolutions provider in NorthAmerica, as well as H2O Jet Inc.,a US-based manufacturer anddistributor of pumps, spare partsand components for waterjetequipment including diamondnozzles. The combined annualrevenue of the acquired companiesamounts to approximately SEK(Swedish Krona) 300 million.

As a result of the acquisitions,KMT becomes a global leader inrobotic waterjet and trimmingapplications, including waterjetpumps for automotive applicationsand the spare parts market. KMTalso gains process knowledge intrimming applications outsidewaterjet technology, such as lasercutting and router- and knife-trimming. Through the acquisitionof RPT, KMT Cutting Systems willhave a global reach and its saleswill more than double. RPT’sgrowing non-automotive businessprovides KMT with a greaterability to access this business inboth Europe and North America.

“By combining KMT CuttingSystems’ and KMT WaterjetSystems’ existing organizations,international experiences anddistribution channels with RPT’sstrong brand, and H2O Jet’s strongknow-how in nozzle technology, wesee considerable growthopportunities globally. Moreover,the acquisitions of RPT and H2OJet will create cost synergies withKMT’s Waterjet Product Area, aswell as providing access to newexciting market segments withsignificant potential,” says LarsBergström, president and CEO ofKMT.


Both companies were consolidatedin the KMT Group as of December 1,2006, as part of the Waterjet ProductArea, where RPT will be consolidatedwith KMT Cutting Systems, and H2OJet with KMT Waterjet Systems. Thetotal purchase price for bothcompanies amounts to USD $36million, with an additional earn-out ofmaximum USD $2 million based onthe financial performance for the year2007. The acquisitions will befinanced through a bank loan. Apreliminary acquisition analysis will bereported in the year-end report,scheduled for release on February 15,2007.

The two acquisitions will have anegligible effect on KMT’s profits in2006, but will have a positive impacton earnings from 2007 and onwards.Management for both companies willremain working for KMT followingthe acquisitions.

Privately owned RoboticProduction Technology (RPT), based

in Auburn Hills, Michigan, is a leadingturnkey robotic manufacturing systemsprovider in North America.Established in 1986, the companyspecializes in high precision trimmingapplications such as waterjet cutting,router trimming and laser cutting. Theserved market segments includeaerospace, appliance, automotive,composites, construction, consumergoods, marine and plastics industries.The global market size for its businessis estimated to be USD $100 millionwith an estimated annual growth rateof 3-5%. RPT has a staff of 80employees and an annual turnover ofapproximately USD $35 million withgood profitability. The business has aninstalled base of approximately 3,000robotic systems.

H2O Jet Inc., founded in 1991 andbased in Olympia, Washington, is aprivately owned custom manufacturerof high pressure waterjet cuttingproducts and waterjet pumpreplacement parts. H2O Jet is a


hen Portland, Oregon, neededto increase the flow rate

through one of its sewer lines, the citydecided to put a sleeve in the line toreduce the pipe diameter. In order toslip the sleeve into place with a goodfit, CCS (A Division of PNE Corp.),was called in by the lead contractor toclean the existing 102-inch diameterline.

Based in Longview, Washington,CCS has a total of five officesthroughout the northwest. CCS’s mostdistinct operations includeenvironmental emergency response(land and marine), industrial cleaning,commercial sweeping, hazardous andnon-hazardous disposal andenvironmental and ecological services.

Portland Cleans Sewer Line With High Pressure Waterjets

“The project was tailor made forone of our Jetstream high pressurepumps,” says Matt Worel, Longviewdivision supervisor for CCS. “Wehooked up a 2D head to a rigid lance.”

The 2D head was designed to sprayhigh pressure water in two horizontaldirections in a way that covers theentire circumference of the interior ofthe pipe, according to Worel. The 2Dhead involved a standard rigid lancewith a T connection at the end. Eachside of the T extended out from thecenter and was mounted with a headattachment that directs the spray. Asthe head was spun, the water blastcovered the full diameter of pipe.

“The challenge then was how to pull700 feet of hose through the sewerline,” says Worel. CCS has tackledprojects like this in the past and thesolution they developed involvesattaching the head and lance to thebucket of a skid steer loader with the

hose trailing behind. With the sewerline opened at both ends, the crewwas able to lower the skid steer loaderinto one of the openings and moveforward to the second opening whilecleaning the pipe as it went.

To begin the cleaning once the skidsteer loader was in position, theoperator raised the bucket so that itwas approximately in the center of thepipe. This was low enough to give theoperator excellent visibility over thebucket and high enough for the spray toclean the entire interior surface of thesewer line wall as planned.

With the lance in position on the raisedbucket, the operator began the cleaningoperation, using the muscle of the skidsteer loader to pull the hose behind themachine.

“Using the skid steer loader moves thehose more efficiently and is less laborintensive,” says Worel.

10,000 PSI powers away build-up

The cleaning project involved aJetstream 10,000 psi, 260 horsepowerdiesel-powered high pressure pumpequipped with a work bench and vise.While the unit is equipped with a

conversion feature thatallows it to be set up for ashigh as 40,000 psi, thisapplication required alower psi, reports Worel.

CCS relies on itsJetstream high pressurepumps at or near the40,000 psi mark whenworking on projects suchas heavy tank cleaning ora surface prep project.They also report usinghigh pressure waterjetswhen preparing steel for x-ray and inspection.

Skid steer loader emerges fromsewer line after pulling hose fromJetstream high pressure pump usedin the cleaning of the pipe’s interiorsurface.

Jetstream high pressure pump delivers the waterjetsneeded to clean a section Portland’s sewer line inpreparation for the installation of a sleeve.

Among the more unusual projects CCShas been called upon to perform, was thecleaning of grain from the hold of a ship. Inthis case, the project involved some of thecompany’s six Guzzler vacuum loaders.

“We rely on newer equipment,” saysWorel. “When municipalities aredepending on you 24/7 for emergencywork, you have to show up withequipment that works.”

“Minor breakdowns are inevitable whenthe equipment is used as often as ours, butJetstream makes it easy to repair on thespot, so we don’t lose much time on thejob,” adds Steve Johnson, IndustrialServices Division manager for CCS. “Therelationship between CCS and Jetstreamkeeps us coming back. We know they arethere to serve us, and they go above andbeyond to answer our questions and make

Portland Cleans Sewer Line With High Pressure Waterjets, from page 6

sure we have a full understanding of howtheir product will help our business grow.”

“Each year we purchase a new Guzzlerto provide our customers the benefits ofthe features this equipment has to offer,”says Johnson. “We pride ourselves onsafety and training at CCS, and value thetraining techniques Guzzler has offered.”

“Like Jetstream and Guzzler, Vactor isalso a step ahead in quality andproduction. Its training technique is anasset to our new hire training program,”reports Johnson.

“With constant industrial and mill typework, CCS knows the importance of astrong fleet,” says Johnson. “The FederalSignal brands, like Jetstream, Guzzler andVactor, provide CCS with thedependability and power we’ve come toexpect from our equipment.”

ne of the nation’s largest steeringwheel trim die manufacturers routinely

cuts 4 to 6-inch thick heat-treated steel withabrasive waterjet.

If you´ve driven a car, truck or SUV lately,chances are the trim die used to make yoursteering wheel was manufactured by Trim Tool& Machine, Inc. of Cleveland, Ohio.

In business since 1999, Trim Tool & Machineis a traditional mom and pop shop that offersabrasive waterjet cutting, CNC milling, stampingand diecast tooling, and machine building. Theeight-person company serves a wide range ofindustries, from automotive to arts andarchitecture, and prides itself on its ability toturn work around within two to three days of anorder, or even the same day, if necessary.

“We turn work around for people,” saysowner Dane Willis. “We get it in there and getit done. If the customer needs it today, we get itdone. I will stay late and operate the equipmentmyself. We do the job when we say we aregoing to do it.”

Trim Tool & Machine specializes in gages,fixtures, trim dies, special machines, custommetal art and repairs, but is best known as oneof the largest producers of steering wheel trimdies in the United States. In fact, the companyhas produced trim dies used by nearly everyauto manufacturer in the country.

A trim die is a specialized stamping tool madeof thick hardened steel that is used to trim awayexcess metal from diecast castings, creatingprecise and consistent parts. While manycompanies use wire EDM to cut their trim dies,Willis says he uses a Jet Edge abrasive waterjetsystem because it is much faster and more cost-effective.

“That gives me a competitive edge,” Willisnotes. “With waterjet it costs $3 to $5 to cut

one inch versus $10 to cut with wire. It’s two-thirds more to wire cut something. You canutilize waterjet for about 85 percent of the die.”

While waterjet is best known for cuttingthinner materials, Trim Tool & Machineroutinely uses their system to cut thickhardened metals, including 9-inch thick 4140heat-treated steel.

“We typically cut 4 to 6 inches all day long,”Willis says. “Anyone that comes in says ‘wow,you cut thick.’ We cut more thick steel thananybody. We design around it, and utilizespacers, if necessary, to reduce the taper.”

Five years ago, to set himself apart from thecompetition, Willis invested in a 4-foot by 8-footprecision high-rail gantry waterjet systemmanufactured by Jet Edge of St. Michael,Minnesota. The machine is powered by a 50-

“I bought the largest and best one Icould,” he says.

Willis researched numerous waterjetsystems for several years beforedeciding on Jet Edge. The system’sbridge-style overhead gantry appealedto him, as did Jet Edge’s commitmentto customer service.

“I was a one man show, and to beperfectly honest, Jet Edge was one ofthe only companies that talked to me,”he recalls. “It looked like it wasconstructed better, and uponresearching it, everyone raved aboutthe pump.”

Willis says Jet Edge has exceededhis expectations, and that when afriend asked him what type ofmachine he should buy, he told him hecould only recommend threemanufacturers, but that he would gowith Jet Edge over the other two,mainly because of the company’sexcellent support.

“Jet Edge has been very good,” hesays. “The support has been good, thesales staff has been great and theservice staff has also been great.”

Willis says his Jet Edge system hashelped him increase productivity andreduce costs, saving customers’thousands of dollars and enabling himto expand his business.

“We have been able to maintain thecost of tooling despite the steel

increase because we are usingwaterjet,” he notes.

Willis recalled one project where acustomer needed to have twenty-eight .281- inch holes cut in half-inchthick hardened A-2 material. He

was able to do the project for only$90 with his Jet Edge system.

“For someone to burn it or carbideit, it would have been hundreds of

dollars,” he says. “Waterjet can tackle hardenedsteel.”

Trim Tool & Machine also has saved itsstamping industry customers thousands of dollarsby using its Jet Edge system to cut precisestamping strips that customers can use to makesample hits prior to making final adjustments tothe cuts in the die.

“It saves them thousands of dollars in tryouttime,” Willis says. “The waterjet mimics thestamping process perfectly. Laser and plasmaleave a case-hardened edge. When I talk acustomer into waterjetting, they never go back tolaser or plasma.”

Willis notes that his Jet Edge system hasresulted in a huge boom to his business, and thathis sales doubled the first year after he boughthis waterjet.

“At that point I was able to start hiringpeople,” he says. “I believe I would not havesurvived the post-911 industrial crash if I hadn’t

had the waterjet. Without the waterjet, there is no way we wouldhave been able to grow.”

Robotized abrasive waterjet cuttingis designed for cutting harder materialssuch as metals, glass fiber andceramic materials. A fine abrasive isadded to the high-pressure waterjet,which cuts materials through aprocess of microerosion. Typicalindustrial applications includedeburring and grinding of castings,trimming of titanium alloys, glass fiberand composite details or cutting largermetal tubes.

KMT Cutting Systems AB, a fullyowned subsidiary of the industrialgroup, KMT, is a leading supplier ofrobotized waterjet cutting, routing andcleaning systems to the automotiveand general industries.

pioneer in the development ofdiamond nozzle technology forUltra High Pressure (UHP)applications – as one of only twocompanies in the world – and leadsthe industry in the implementationof this extremely durable and costeffective technology. In addition,H2O Jet supplies components andreplacement parts for waterjetcutting equipment, along with theH2O Jet family of AdvantageUHP Intensifier Pumps. H2O Jethas a staff of 30 employees andannual sales of approximatelyUSD $10 million, of which themajority of sales are derived fromthe aftermarket segment. Thecompany enjoys good profitability.

Enhanced Abrasive Waterjet (AWJ) Cutting Through Modulation


he research community of thewaterjet industry is constantly

striving for improvement ofproductivity and quality of cut. One ofthese efforts was from Henning andWestkamper*, on enhancing AWJcutting through modulation. Here arethe highlights.

Two main characteristics that affectAWJ quality of cut are jet lag andstriation marks. Striation marks mainlyaffect the appearance of the partwhile jet lag will cause inaccuracyaround corners and small arcs.Currently reduction of jet lag andstriation is done by reducing thecutting speed. In this experimentalstudy, three kinds of modulation weretested, targeting reduction of jet lagand striation without reducing thecutting speed. Two of these weredone by superimposing a constantlinear cutting speed with a sine-oscillation, parallel or perpendicular to

the cutting direction. The averagecutting speed was kept unchanged.The oscillation frequency varied from0.5 to 3 Hz and amplitude from 0.3 to1.2 mm. The third modulation wasdone by periodically interrupting theabrasive flow while maintaining thesame average flow rate. Theinterruption frequency was 1 Hz. Theproportion of Off time-vs-On timevaried from 1:2 to 1:10.

Among the three modulations, theparallel oscillation has the mostfavorable impact on jet lag andstriation. Significant jet lag reductionswere shown for all the testedoscillation frequencies and amplitudeswhile low frequencies were slightlybetter.

Perpendicular oscillation andabrasive modulation also showed slightreduction of jet lag. Striationmagnitude was also reduced with

parallel oscillation, but not assignificant as the jet lag reduction.Small oscillation amplitudes (0.3 and0.6 mm) and high frequency (2.5 Hz)produced the best result for striationreduction. Striation got worse withperpendicular oscillation and togglingabrasive had a mixed result, with thebest result achieved at 1:6 OFF/ONratio. For overall performance paralleloscillation at high frequency and lowamplitude was recommended.

his article reviews the work ofV. Cutler* on the use of AWJs

for glass artworks.

Abrasive waterjet cutting oftenrequires piercing starting holes. Thesestarting holes are made by allowingthe jet to dwell long enough to go allthe way through the material. A blindhole can be made by controlling thetime of pierce.

Cutler made an array of such blindholes on a piece of glass to create aneffect of “a bed of white nails buryingthemselves into the material”(pictured above). To avoid crackingthe glass, piercing should be done atlow pressure. However, cracking canalso be caused by internal stresses ofthe glass. Cracking caused bystresses can occur right away or at amuch delayed time. These cracksoften initiate at top surface or halfwaybelow. A piece of highly stressed glasscan be identified under aspectrometer, which makes the stresscondition visible to human eyes. Theglass should be annealed fullythroughout before piercing andcutting.

AWJs were also used by Cutler tocut joined-up text and handwrittentext to create glass artworks designedby other artists. A joined-up textartwork was made on a piece of 6

Innovative Uses Of Abrasive Waterjets (AWJs) For Glass Artworks

mm thick Float glass, 2400 mm inheight and 700 mm in width. Itconsists of the text “I am fine” inTimes New Roman font and indecreasing scale as it ascends theheight (pictured below). Once cut itwas slumped to create an irregulareffect.

Another piece of artwork wasjoined-up handwritten text. This typeof artwork presents several challengesto abrasive waterjet cutting. Fragilitywas one. Because the thickness of thelettering varied between 1 and 4 mm,the work was extremely delicate anddifficult to move once cut. Stabilitywas another. The fragility of the glassmade the entire shape unstable andthe handling difficult. Programmingwas very complex, especially for thehandwritten text. Because of limitationof the machine and also the risk

associated with various factors (e.g.operator fatigue, abrasive shortage,etc.), the cutting was broken down toseveral programs.

Another innovative use of AWJswas to create “Scribbles” on glass(see below). The complexity ofprogramming was emphasized.

WARDJet’s Pneumatic Drill Mount

W


aterjet cutting can be avaluable tool to many

fabricators, but there are certainmaterials that have always provendifficult to work with. Some materialssuch as laminated shim stock, certainlaminated composites and phenolics,may de-laminate during the waterjetpiercing process. WARDJet’sPneumatic Drill allows a hole toautomatically be drilled through thematerial at a specific offset from thewaterjet cutting head. Once the holeis drilled, the waterjet will then startthe cut inside the pre-drilled hole. TheCAD/CAM program, IGEMS, canautomate this entire process. In orderto use this tool, an air compressorcapable of 25 cfm at 90 psi must beprovided. This will allow thesematerials to be cut regardless of anynecessary holes.

This unique drill feature also comesin useful when cutting high toleranceholes in various steel and stainlesssteel materials. By using the reamingcapabilities, a customer can pierce theinitial hole with the waterjet and thencome back and ream it out to get thehigher tolerances that are required.This can be substantially faster than

using a waterjet alone to create thesehigher accuracy holes.

The pneumatic drill feature isavailable to be mounted on anyWARDJet waterjet cutting system.This is just one of many uniquefeatures that WARDJet offers toallow their waterjet to be used in avariety of applications. If you have adifficult application, give WARDJet acall and see what they can offer asthey work with you and your team tofind the best solution possible.

Jetstream Upgrades Durasafe Control Gunsetstream of Houston recentlyreleased improved handle

assemblies for the popular DuraSafeseries of hand control guns. Theupgrades feature a redesigned triggerlinkage that reduces the forcerequired to properly engage the valveby fifty percent.

Standard on all new DuraSafe shut-in and dump style hand control guns,the new handles are also available assimple bolt-on retrofits for existingguns to take advantage of theimprovement.

“The reduction in required triggerforce lessens operator fatigue andincreases valve cartridge life bymaking it easier for an operator tomaintain the force needed to securelyengage the valve,” says Mike Bullard,parts marketing specialist, Jetstream.

“We spend a great deal of timelooking for ways to reduce the energyrequired to perform waterblastingtasks because evidence clearlyindicates that it helps the operatorremain more alert and allows them towork more safely and effectively.”

Jetstream is widely recognized forseveral significant advancements inwaterblast control gun design, mostnotably the introduction of thecartridge-style valves for fast, easyfield maintenance and hydraulically-

biased valving for safer, more positiveoperator control. The company hasmanufactured innovative control gunsfor more than twenty years andlaunched production of the versatileDuraSafe series in 1998.

Jetstream manufactures industrialhigh-pressure waterblasting equipmentfor pressures up to 40,000 psi (2750bar) for use in a wide range ofapplications, including industrialcleaning and surface preparation.Product offerings include a completeline of skid- and trailer-mounted pumpunits, control guns, valves, nozzles,hoses, and replacement parts.
