A milling machine is a wheel-cutting machine, dating from the 1700s and used by clockmakers, were the precursors of industrial milling machines. Eli hitney is most often mentioned as the first to design and construct a milling machine that was dependable, and which served as a prototype for later, improved cutting machines.

2. INTRODUCTION TO GRINDING PROCESS • • • It is the only economical method of cutting hard material like hardened steel. It produces very smooth surface, suitable for bearing surface. Surface pressure is minimum in grinding. It is suitable for light work,which will spring away from the cutting tool in the other machining processes.
MACHINNING TIME The cutting speed,feed, length of cutting stroke, breadth of the job and number of double strokes per minute for a planer operation are known, the machining time required for one complete cut may be calculated. Time = W/F.N F = feed per stroke. N = no. of stroke per minute. 33.
5. Each machining operation produces a characteristic part geometry due to two factors: 1. Relative motions between tool and workpart • 1. Generating – part geometry determined by feed trajectory of cutting tool Shape of the cutting tool • Forming – part geometry is created by the shape of the cutting tool. 6.
