In the market of cutting tools, I feel that there is a big confusion between HSC and HPC.
Some person (especially people from university and research center) say that High Speed Cutting is the same thing that High Performance Cutting.
For me, High Performance Cutting is a method where the axial and radial depth of cut are very high (ap > 1xD, ae = 1 x D) but the cutting speed is relatively slow. With this method, you can obtain very high metal removal rate.
And for you, what is High Performance Cutting ??
