Grinding is used for-
Surface finishing
This makes Surface finishing the most appropriate description of its primary use. As the table illustrates, grinding stands out for its focus on the final quality of the surface and the tightness of the dimensions, aligning perfectly with the concept of Surface finishing .
When the file is pushed and pulled across the work, it is called:
A copper bar of diameter 200 mm is turned with a feed rate of 0.25 mm/rev with depth of cut of 4 mm. Spindle speed is 160 rpm. The material removal rate (MRR) in mm3/s is :
The manufacturer has marking on a grinding wheel as ' A 36 L 5 V'. The code 'V' represents the:
A 20 mm diameter through-hole is to be drilled in a 30 mm thick plate using a double fluted, 120° lip angle drill. The drill tip is at a distance of 3 mm from the plate surface when cutting started and an over travel of 2 mm is recommended. If the drill rotates at 500 rev/min and the feed per revolution is 0.1 mm, the machining time of operation (in sec) will be
