1.

Open Pro/Engineer and Draw a block 2”x 3” x 2” deep

2.

Make a sketch on one of the 2” x 3” surfaces

3.

Draw and extrude something to be machined out. If you want to type your initials, click on the

text icon in sketch mode, and draw a VERTICAL line from Bottom to Top (the text will be slanted

if you draw the line as a slant, the text will be upside own if you draw the line from the top to

the bottom, and oriented 90 degrees if the line is horizontal). Enter your initials in the text

window and press OK. Middle Click to display dimensions. Enter the appropriate values for the

dimensions. Press the check mark to exit sketcher mode. Extrude sketch to 0.25 inches.

4.

Save your initials

5.

Go to File>New>Manufacturing and give it a file name (I typically append _mfg after my part

name) and press OK






6.

Go to Insert>Reference Model>Assemble to insert your part model. Select your part and click

Open. Change from automatic constraint to default constraint . Click on the check box. A

dialogue box will pop up. Click ok.






7.

Insert the coordinate axis by clicking on the coordinate system button. Select the rightmost

surface, press and hold control, click on the backmost surface and the topmost surface, in that

order. (Note where the top surface is on the figure) Make sure ‘X’ is point right, ‘Y’ is point back,

and ‘Z’ is point up. Flip the coordinate axis from the orientation menu if needed. Click OK when

done.






8.

You will now make your operation. Click on Steps>Operation

9.

Click on machine tool dialogue and press OK

10.

Click on the arrow icon next to Machine Zero and click on the coordinate system that you just

made






11.

Click on the arrow next to Surface and type in “0.25”. Make sure the retract plane is ABOVE your

part, as shown in the screenshot. PLEASE NOTE THAT THIS VALUE WILL BE LARGER IF YOU ARE

CLAMPING YOUR PART FROM THE TOP, SINCE THE ENDMILL MUST CLEAR THE CLAMP . Press

OK to set the retract plane, press OK to exit operation setup.






12.

Insert the desired machining sequence. We are doing a pocketing sequence for this example.

Click on Steps>Pocketing. On the Menu Manager, click ‘Done’. Enter a endmill diameter (choose

from 0.25 inch or 0.125 inch and press “Apply”. Click OK to go to parameters

13.

Enter ‘30 for cut_feed, half your selected endmill diameter for step_depth and step_over (e.g.

0.0625” or 0.125”) Scroll down on the parameter list and enter 0.25 for clear_dist and 10000 for

spindle_speed. Press OK when done.






14.

Make sure Model is selected and click on Done. . Make sure “Add” is selected. Select the

“Bottom” surface Press and hold ‘control’ and click on all the associated perpendicular surface.

Press “Done/Return” when finished. Press Done Seq to exit out of the menu manager.

15.

To check your sequence, right click on the sequence, select ‘Play Path’ . Move the display speed

over to ‘slow’ and press the play button. Make sure all the surfaces have been machined.






16.

If none of the surfaces have been machined, your coordinate system may not be in the right

orientation. You may need to flip your coordinate system (right click on the coordinate system in

the model tree, select “edit definition” and see step 7 in this tutorial). Otherwise, You may need

to re-select your machining surfaces. To do this, right click on the sequence, and click “edit

definition”. Select “Sequence Setup” from the menu manager” Click on “surfaces” and “done”.

Make sure Model is selected, and click Done. Repeat step 14 for the missing surfaces.

17.

If only certain parts of the model is machined and not others, you may of used too large of an

endmill. Select your sequence, right click on “edit Definition” Click on Sequence Setup. Select

“Tool”, and “Parameter” and click on “Done. Repeat steps 12 and 13.

18.

When everything seems good. You may output your g-code sequence. Click on Edit >CL

Data>Output (You have to scroll all the way down in the edit menu) Click “NC Sequence” and

click on the desired sequence. Click on File, check the “MCD” box, click done. Type in a name for

the sequence and press ‘OK’






19.

Click on the “UNCX01.P11” (or whichever is listed first under ‘PP LIST’). Press Enter when it asks

for program number. Click Close on the information window. Click “Done Output” on the menu

manager.






20.

Open Notepad from your computer. Click on File>Open, select “all files” and select your

sequence name file appended with “.tap”






21.

Delete the second, 3rd

, and 4th

line of the g-code file. Type ‘G90 G20’ on the second line, and

‘G00 Z0.5’ on the 3rd

line. Make sure the letters are all capitalized. Click File>Save As change file

type to all file. Change extention to “.ncd” and click Save.






22.

Repeat steps 18-21 for all remaining CAM sequences. Remember the size of your endmill, and

where your coordinate axis is, in relation to your part, and remember to bring your file when

you machine out your part.
