milling cutter in a conventional horizontal arbour type milling machine. The G and D are connected here with the tool work motions as. G – x – T – F. D – FM – W – T.Tr. CM – T. Here G and D are independent of the cutting motion and the G is the line of contact between the milling cutter and the flat work surface. The present.

The cutting motion in drilling machines is attained by rotating the drill at different speeds (r.p.m.). Like centre lathes, milling machines etc, drilling machines also need to have a reasonably large number of spindle speeds to cover the useful ranges of work material, tool material, drill diameter, machining and machine tool
Machine Tools: (ex- Lathe m/c, presses, milling m/c etc). ? Some objects made of a combination of several parts, made from a variety of materials (ex- bicycle, computer, car:15000 parts etc). ? Manufacturing is a complex activity that involves : people, machinery, tooling with various levels of automation. (computers, robots
o Shock initiated cuts in shaping machine, planing machine, slotting machine etc. are conducted at lower VC o Intermittent cuts, as in milling, hobbing etc. are done at quite lower speed for dynamic loading. • Work material (type, strength, hardness, heat resistance, toughness, chemical reactivity etc.) For instance; o Harder

ACCESSORIES : A general purpose machine tool is basically comprised of power drive and kinematic system for the essential formative and
(i) Name the general purpose machine tools of common use. (ii) Classify the different types of lathes. (iii) Illustrate the kinematic system of centre lathe and explain its method of working. (iv) State the different machining operations that are usually done in centre lathes. (i) General Purpose Machine Tools Of Common Use.
The basic function of milling machines is to produce flat surfaces in any orientation as well as surfaces of revolution, helical surfaces and contoured surfaces of various configurations. Such functions are accomplished by slowly feeding the workpiece into the equispaced multiedge circular cutting tool rotating at moderately
Radial or transverse force, PRi (equivalent to PXY in turning). • R is the resultant of PT and PR. • R is again resolved into PZ and PY as indicated in Fig. 8.4 when Z and Y are the major axes of the milling machine. Those forces have the following significance: o PT governs the torque, T on the cutter or the milling arbour as.
