Appl. No.:

11/020823

Inventors:

Toan Tran - Houston TX, US

International Classification:

B23C 5/00

US Classification:

407033000, 407066000

Abstract:

The outer diameter roughing in a CNC lathe turning process utilizes generally inserts with zero degree negative clearance angle (N−0 degree Negative) for economic purposes. The common roughing tool holder is using the diamond shape insert, the so called CN_or DN_insert. In a variation of these conventional tool holders only one corner (mostly 80/55 degree) of the insert is in cutting operation. The other corner (110/125 degree) could be reused in another tool holder.
