TRENDS
The major trend in cutting processes is to optimize operations and minimize costs by automation,reducing the amount of labor needed.
High-speed machining (with spindle speeds on the order of 20,000 rpm) and hard turning are in wider use and are becoming competitive with other removal processes in specialized application.
Much progress is being made in the ultraprecision machining of components using very sharp single-crystal diamond tool.
Sensors for measuring and monitoring forces,power,deflection,temperature,tool wear and fracture,and surface finish are in use as a means of on-line compensation to maintain quality and reduce defective parts。
