Optical Profiler Analysis of Cutting Tool Wear During High Speed Machining

From Veeco Instruments
 

 

High speed machining not only saves manufacturing time and obviates certain finishing steps, but it also helps to produce parts with higher strength. The need to machine parts faster has lead to the use of higher machining speeds, as well as a need to understand the impact of the resultant stresses on mechanical part surfaces.

High speed machining is routinely used in many manufacturing environments, including the automotive and avionics industries. In these fields there is a strong and increasing interest in understanding the cutting process and in optimizing the coupling between cutting tool and machined material. Characterizing the surfaces of tools before and after machining provides data that can lead to even higher speeds and longer cutting tool life.

Numerous instruments and software simulation packages have been routinely used to qualify and improve the cutting process. However, few studies have focused on the direct observation of the surface of the cutting tools.
