Cutting Parameters Cutting Speed The cutting speed (V) of a cutting tool is the speed at which the metal is removed by the tool from the work piece . In a shaper the cutting action is intermittent hence in shaper the cutting speed is considered only during the forward cutting stroke
Cutting Paramete rs Machining Time If the length of cutting stroke, breath of the job, feed and cutting speed are known, the time required to complete the job may be calculated as; Let; L = the length of the stroke in mm B = the breath of the workpiece in mm f = the feed in mm/double stroke m = the ratio between the return time to the c utting time V = the cutting speed in m/min
Planing Machine tool
Introduction Planer is a machine tool, which removes the metal from a piece of work to the required shape & size. It is mainly intended to produce any surface composed of straight line elements. Cutting Tools are Stationary and Work piece is Reciprocating Intermittent Cutting Process Metal is Removed in the form of Chips planer is a 2D machine Uses Single Point Cutting Tools

A planer is a versatile machine tool primarily designed to generate a flat surface by a single point cutting tool. But it may also be used to perform many other operations. The different operations which a planer can perform are as follows: 1. Planing Flat Horizontal Surface 2. Planing Vertical Surface 3. Planing at an Angle and Machining Dovetails 4. Planing Slots and Grooves 5. Planing Curved Surfaces Planer Operations
