Shaper Machine
Shaper Machine
Process of removing metal from surface by the use of a single point cutting tool held in ram that reciprocates the tool in a linear direction across the work piece held on the table of the machine
Types of Shaper Machine
• Horizontal Shaper Machine• Ram along with tool moves in Horizontal
Direction• Vertical Shaper Machine Ram along with tool moves in Vertical Direction
Components of a Shaper Machine
• Base• Column• Table• Ram• Tool head
Tool head
Driving Mechanism in Shaper Machine
• Mechanical Ram Drive• Automatic Feed Motion• Hydraulic Drive
Mechanical Ram Drive
Automatic Feed Drive
Hydraulic Drive
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
Slotting Machine
Slotter Machine
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
Slotted Disc Drive
Operations done in Slotter
• Machining flat surface• Machining cylindrical surface• Machining irregular surface and
cam machining• Machining slots, keyways and grooves
Surfaces Machined in Slotter and Shaper Machines
Planer Machine
Components of a Planer Machine
• Bed• Table• Housing• Cross rail• Tool heads
Types of Planer Machines
• Double Housing Planer• Open Side Planer• Planer Miller• Pit type Planer
Double House Planer
Open Slide Planer
Drive Mechanism
• Hydraulic Drive• Variable Speed Motor
Work Holding Devices in Shaper, Slotter and Planer Machines
Cutting Speed, Feed and Depth of Cut in Planer, Shaper and Slotting Machine
Cutting Speed, V = L*N(1+K)/1000 m/min Where L = Length of arm stroke, mm N = Number of full strokes/ minfull stroke means Working and return stroke K = Ratio of return time to cutting time
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
f = feedd = depth of cut
