INTRODUCTION A shaper is a machine tool that uses

reciprocating straight line motion of the tool and a perpendicular feed of the job or the tool.

With special tools, attachments and devices for holding the work, a shaper can also be used to cut external and internal key ways, gears, racks, dovetails, T-slots and other miscellaneous shapes.

Shaping is essentially an inefficient method of metal removal but the simplicity

Introduction to shaper &planer machine, NC- CNC machine

The most common type of horizontal shapers is the production push cut shaper.

The reciprocating motion of the ram provides the straight line motion to the tool which is the speed for cutting.

The vertical movement of the cross rail permits jobs of different heights to be accommodated below the tool and is a machine setting.

3. Hydraulic shaper mechanism

Shaper Mechanism

Parts of a standard shaper

The planer is almost exactly similar to a shaper, and is primarily intended to produce plane and flat surfaces by a single point cutting tool .

Planer

The slotter machine operates almost on the same principle as that of a shaper.

The slotter is used for cutting grooves, key ways, and slots of various shapes, for making both internal and external regular and irregular surfaces.

Slotter

Numerical control or computerised numerical control is a technique of automatically operating a productive facility based on code of letters, numbers and special characters .

The complete set of coded instructions; responsible for executing an operation is called part programme.

All NC/CNC machine tools are provided with drive motors and other accessories to do auxiliary functions of the machine along with the work table, spindle and other hardware of the traditional machine tools.
