Question

Select All correct choices with regards to conventional milling.

*The cutter tends to pull the workpiece away from the table.

*The cutter tends to push the workpiece onto/into the table

*the thickness of the chip is maximum at the beginning and decreases along the length

*the thickness of the chip in the beginning is zero and it increases along the chip length

Answer 1

In the milling operation the milling cutter pushes the workpiece onto or into the table as the cutter is often on the top and the cutting force can be assumed to be vertically downward .

Again at the beginning of the cutting operation as the milling cutter revolves , the chip thickness is zero and it gradually increases and becomes maximum at the middle and then again gradually decreases to zero at the end. This happens because when the first teeth of the milling cutter touches the workpiece the depth of cut is almost zero and it gradually increases along the workpiece.
