A mild steel block of width 40 mm is being milled using a straight slab cutter 70 mm diameter with 30 teeth. If the cutter rotates at 40 rpm, and depth of cut is 2 mm, what is the value of maximum uncut chip thickness when the table feed is 20 mm / min?

In a orthogonal machining, the shear angle is 22° and rake angle is 11°, then the shear strain is _____

In a turning operation with orthogonal machining, the rake angle is 12° and the coefficient of friction at the tool chip interface is 0.60. If the spindle rotates at 300 rpm and tool is fed at 0.4 mm per revolution, then the value of chip thickness is _____ mm (Take depth of cut = 0.6 mm) 

 The surface of a metal slab of 278 mm length and 80 mm width is machined by a face milling cutter of 120 mm diameter, having 10 teeth, rotating at 50 rpm. The milling feed is 0.1 mm/tooth of the cutter. The combined time for job loading and unloading is 2 min. The approach and over travel of the tool are 1 mm each then 

In plunge surface grinding a steel specimen of 2.5 mm width and 200 mm length is ground with A-A-6-0-K-5-V-8 grinding wheel of 300 mm diameter and 25 mm wide. The wheel has undergone a radial wheel wear of 20 microns after removing material to a depth of 5 mm.
