With the SMC function, the error can be automatically corrected, and it can be matched according to the specified parameters of speed, precision, and smoothness, and there is no need to wait for professional engineer. For different machining workpieces, there are different requirements for cutting speed, precision and surface finishing. How to quickly set the optimal parameters? The SMC function provides different options that base on different machining conditions for users, it can reduce machining errors and increasing cutting efficiency.
