This animation shows the working of a shaper machine.
The shaper machine is used to create plane surfaces on any workpiece.
The tool is used to cut metal by the reciprocating motion of the ram
[Stuttering.., Sorry]
This mechanism is in fact an application of the slider crank mechanism and its oscillating cylinder inversion.
The animation shows how the rotary motion of the motor is transformed into the reciprocating motion of the ram.
The bull gear which is connected to the motor is in white, the frame of the machine is green.
The rocker arm is red, the ram is blue and the tool is grey in colour.
The tool is attached rigidly to the ram via the toolpost.
The tool reciprocates in such a way that the return stroke is faster than the forward stroke.
The rocker arm oscillates back and forth on the pivot of the frame.
The rocker arm converts the rotary motion of the bull gear to the oscillating motion of the ram.
The rocker arm oscillates the ram.
The special feature of the mechanism here is in fact that the return stroke is quicker than the forward stroke.
The requirement of any shaper mechanism is that it should have a quick return stroke.
This mechanism satisfies that requirement.
The quick return stroke is required for machining cost reduction.
To increase the stroke length, the crank radius of the bull gear is increased.
And to adjust the position of the tool the pin on the ram can also be adjusted.
