Working Principle:

• In a shaper machine, the workpiece is stationary, while the cutting tool has a reciprocating motion.
• The cutting tool is clamped in the tool post, and the workpiece is held tightly on the table. Shaper is primarily used to produce flat, smooth surfaces with special attachments.
• They can also produce internal and external keyways, gear racks, spiral grooves, T- slots, etc.
• It states that the cutting tool travels back and forth over the work for machining.

Advantage:

• Less time and skill is required for setting the work.
• The cost of the machine is less.
• These are light in construction.
• These require less floor space area.
• The speed of the shaper varies throughout the work.
• The simple tool is used i.e. single cutting point tool.
