SHAPER, SLOTTER & PLANER MACHINE
SHAPER MACHINE A SHAPER SHAPER IS A MACHINE TOOL TOOL THAT THAT USES RECIPROCATING RECIPROCATING LINE MOTION OF THE TOOL AND A PERPENDICULAR FEED OF THE JOB OR THE TOOL.
SHAPER MACHINE A SHAPER SHAPER IS A MACHINE TOOL TOOL THAT THAT USES RECIPROCATING RECIPROCATING LINE MOTION OF THE TOOL AND A PERPENDICULAR FEED OF THE JOB OR THE TOOL.
TOOL HEAD MOVEMENT • THE TOOL POST AND THE TOOL SLIDE CAN BE ANGLED AS SEEN BELOW. THIS ALLOWS THE SHAPER TO BE USED FOR DIFFERENT TYPES OF WORK DIA A: The tool post has been turned at an angle so that
DIA B: The tool post is not angled so that the tool
DIA C: The top slide is slowly feed into the mate rial so that a ‘rack’
side of the material can be machined
can be used to level a surface.
can be machined for a rack and pinion gear system.
SHAPER / PLANER TOOLS The basic assumption to design shaper and planer tool is to withstand high operating impact load. Therefore there are number of different tools used to do machining process a. b. c. d. e. f. g. h.
Straight shank roughing tool Bent type roughing tool Side cutting tool Finishing tool Broad nose finishing tool Slotting tool Tee slot tool Gooseneck tool
ADVANTAGES OF HYDRAULIC DRIVE • OFFER GREAT FLEXIBILITY OF SPEED • SMOOTHER OPERATION • ABILITY TO SLIP WHEN TOOL IS OVERLOADED • ABILITY TO CHANGE LENGTH AND POSITION OF STROKE, WHILE MACHINE IS RUNNING
CUTTING TIME FOR SHAPING • L = LENGTH OF STROKE TO BE SET FOR THE JOB (MM) • 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)
EXAMPLE • ESTIMATE THE TIME REQUIRED TO MACHINE A CAST IRON SURFACE 275 MM LONG AND 100 MM WIDE IN ONE CUT USING A CUTTING SPEED OF 0.33 M/S AND A FEED RATE OF 0.25MM PER STROKE ON A SHAPER WITH A CUTTING-TORETURN TIME RATIO OF 3/2. THE AVAILABLE RAM STROKE ON THE MACHINE 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 BE ROUGH MACHINED USING H. S. S. TOOL ON A CONVENTIONAL CRANK SHAPER. ESTIMATE THE MACHINING TIME ASSUMING AN AVERAGE CUTTING SPEED OF 0.33 M/S AND A FEED RATE OF 0.5 MM/STROKE. THE CUTTING TIME TO RETURN TIME RATIO IS 3:2 AND THE RAM CYCLES AVAILABLE ON THE SHAPER ARE 28, 40, 60 AND 90 CYCLES PER MINUTE.
• T = 14.28 MIN • N = 28 CYCLES/MIN
APPLICATION OF SHAPER • EXTERNAL AND INTERNAL KEY WAYS • HELICAL GROOVES • GEARS • RACKS • DOVETAILS • T-SLOTS • OTHER MISCELLANEOUS SHAPES
SLOTTING MACHINE • A
SLOTTER
IS
NOTHING
BUT
VERTICAL
SHAPER.
• ITS WORK ON THE SAME PRINCIPLE AS OF SHAPER MACHINE.
• THE MAIN DIFFERENCE IS RAM MOVEMENT, WHICH IS IN VERTICAL DIRECTION, WHEREAS IN SHAPER IT IS HORIZONTAL.
• MECHANISM OF SLOTTER IS SAME AS SHAPER
COMPONENTS OF A SLOTTER MACHINE • BASE • COLUMN • TABLE • RAM • TOOL • TOOL HOLDER
TYPES OF SLOTTERS
• PUNCHER SLOTTER • PRODUCTION SLOTTER • TOOL ROOM SLOTTER
DRIVE MECHANISM IN SLOTTER MACHINE
SAME AS IN SHAPER MACHINE, SLOTTER MACHINE ALSO HAVE • HYDRAULIC DRIVE • SLOTTED DISC MECHANISM
SLOTTER ATTACHMENTS • SUCH SIMPLE AND LOW COST ATTACHMENT IS MOUNTED ON THE HORIZONTAL SPINDLE FOR PRODUCING KEYWAYS AND CONTOURED SURFACE REQUIRING LINEAR TRAVEL OF SINGLE POINT TOOL IN MILLING MACHINE WHERE SLOTTING MACHINE AND BROACHING MACHINE ARE NOT AVAILABLE. • THERE ARE SEVERAL OTHER POSSIBLE ATTACHMENTS WHICH CAN BE USED FOR SOME SPECIFIC APPLICATION NOT INCLUDED IN THE BASIC RANGE OF A PARTICULAR MACHINE TOOL.
PLANER MACHINE • A COMMON PLANER IS A MACHINE TOOL DESIGNED TO MACHINE METAL BY COMBINING THE LINE MOTION OF A JOB AND THE PERPENDICULAR FEED OF THE TOOL.
COMPONENTS OF A PLANER MACHINE • BED • TABLE • HOUSING • CROSS RAIL • TOOL HEADS
TYPES OF PLANER MACHINES • DOUBLE HOUSING PLANER • OPEN SIDE PLANER • UNIVERSAL PLANER • PIT TYPE PLANER • PLATE OR EDGE PLANER
DOUBLE HOUSE PLANER
OPEN SLIDE PLANER
DRIVE MECHANISM
• HYDRAULIC DRIVE • VARIABLE SPEED MOTOR
PLANER ATTACHMENTS
Contour forming attachment Other attachments
• Rotary tool driver attachments • Hydraulic tracer control type attachments
Helical grooving attachment
