The workpiece is supported throughout its entire length as grinding takes place.
It is a continuous process and adopted for production work.
It requires no holding device for the work.
All of the above
The cutting edge is inclined at an angle less than 90° with the normal to the velocity of the tool.
Frequently, more than one cutting edges are in action.
The chip flows on the tool face at an angle less than 90° with the normal on the cutting edge.
All of the above
Grinding at high speed results in the reduction of chip thickness and cutting forces per grit.
Aluminium oxide wheels are employed.
The grinding wheel has to be of open structure.
All of the above
Very high pouring temperature of the metal
Insufficient fluidity of the molten metal
Absorption of gases by the liquid metal
Improper alignment of the mould flasks
Increase in coefficient of friction
Decrease in coefficient of friction
