Study of Experiments on Cutting Difficult-to-Machine Materials with Ultrafine-Grained Waved-Edge Milling Insert

Abstract:

For the cutting of the difficult-to-machine materials, such as stainless steel and dead-hard steel, is always puzzling and restricting manufacturing, it is necessary to deeply study and search after new machining methods in respect of both theory and practice. This paper chose waved-edge milling inserts and flat-groove milling inserts of different materials to make cutting force contrast experiments on stainless steel ZG0Cr13Ni5Mo, chose ultrafine-grain inserts, YT14 inserts (local product) and CY250 inserts(foreign product) to make cutting life contrast experiments on dead-hard steel ZG35CrMo, then researched in theory the disrepair appearance, the BSE image and the granularity. The research results show that the integrated cutting capability of ultrafine grain waved-edge milling insert is excellent for difficult-to-machine materials.
