A shaper is a type of machine tool that uses linear relative motion between the workpiece and a single-point cutting tool to machine a linear toolpath. Its cut is analogous to that of a lathe, except that it is (archetypally) linear instead of helical.

A shaping machine is used to machine surfaces. It can cut curves, angles and many other shapes. It is a popular machine in a workshop because its movement is very simple although it can produce a variety of work.
Shaping machines come in a range of sizes but the most common size is seen below.
The main parts are indicated below:
The tool feed handle can be turned to slowly feed the cutting tool into the material as the 'ram' moves forwards and backwards. The strong machine vice holds the material securely. A small vice would not be suitable as the work could quite easily be pulled out of position and be damaged. The vice rests on a steel table which can be adjusted so that it ca be moved up and down and then locked in position. Pulling back on the clutch handle starts the 'ram' moving forwards and backwards.

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 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 feed into the material so that a ‘rack’ can be machined for a rack and pinion gear system.
