SHAPER MACHINE

A SHAPER IS A MACHINE TOOL THAT USES RECIPROCATING LINE MOTION OF TH

PERPENDICULAR FEED OF THE JOB OR THE TOOL.

ALLOWS THE SHAPER TO BE USED FOR DIFFERENT TYPES OF WOR

DIA A: The tool post has been turned at an angle so that

side of the material can be machined

DIA B: The tool post is not angled so that the tool

can be used to level a surface.

DIA C: The top slide is slowly fee

can be machined for a rack and

SHAPER / PLANER TOOLS

The basic assumption to design shaper and planer tool is to woperating impact load. Therefore there are number of different to

machining process

a. Straight shank roughing tool

b. Bent type roughing tool

c. Side cutting tool

d. Finishing tool

e. Broad nose finishing tool

f. Slotting tool

g. Tee slot tool

h. Gooseneck tool

ADVANTAGES OF HYDRAULIC DRIV

OFFER GREAT FLEXIBILITY OF SPEED

SMOOTHER OPERATION

ABILITY TO SLIP WHEN TOOL IS OVERLOADED

ABILITY TO CHANGE LENGTH AND POSITION OF STROKE, WHILE MAC

N = NUMBER OF RAM CYCLES PER MINUTE

V = SUGGESTED CUTTING SPEED (M/S)

r = CUTTING-TO-RETURN TIME RATIO

FEED F, IN PLANING, SHAPING AND SLOTTING IS RELATIVE

MOVEMENT OF THE TOOL IN A DIRECTION

PERPENDICULAR TO PRIMARY CUTTING MOTION PER FULL

STROKE , MM/STROKE

DEPTH OF CUT D, IS THE THICKNESS OF LAYER REMOVED

IN ONE CUT

CROSS SECTIONAL AREA OF UNDEFORMED CHIP = T * B

= F* D

D = DEPTH OF CUT

F = FEED RATE (MM/STROKE)

B = WIDTH OF THE JOB (MM)

NO. OF STROKES REQUIRED TO COVER THE WIDTH = B /T =

60000 min

EXAMPLE

ESTIMATE THE TIME REQUIRED TO MACHINE A CAST IRON SURFA

LONG AND 100 MM WIDE IN ONE CUT USING A CUTTING SPEED OF 0

A FEED RATE OF 0.25MM PER STROKE ON A SHAPER WITH A C

RETURN TIME RATIO OF 3/2. THE AVAILABLE RAM STROKE ON TH

ARE 28,40,60 AND 90 STROKES/MIN.

L = 300 MM

C = 3/5

N = 39.6 STROKE/MIN

NO. OF STROKE NEEDED = 400 STROKES

T = 10 MIN

EXAMPLE

THE 350X200 MM FACE OF A C. I. BLOCK 350X200X100 MM IS TO

MACHINED USING H. S. S. TOOL ON A CONVENTIONAL CRAN

ESTIMATE THE MACHINING TIME ASSUMING AN AVERAGE CUTTING

0.33 M/S AND A FEED RATE OF 0.5 MM/STROKE. THE CUTTING TIME

TIME RATIO IS 3:2 AND THE RAM CYCLES AVAILABLE ON THE SHAP

40, 60 AND 90 CYCLES PER MINUTE.

T = 14.28 MIN

N = 28 CYCLES/MIN

A SLOTTER IS NOTHING

SHAPER.

ITS WORK ON THE SAME P

THE MAIN DIFFERENCE IS WHICH IS IN VERTICAL DIRE

IN SHAPER IT IS HORIZONTAL
