In most NC machining companies, an operator decides the cutting condition, a pair of spindle speed(S) and table feedrate(F), by experience and subjective judgement. We develop a cutting condition decision system for endmills which can automatically determine appropriate cutting conditions and adapt the decision rules based on the machining feedback data.
We discuss identification and specifications of user requirements and functional requirements for the system, the system architecture, a cutting condition decision model, and a cutting condition database. We also explain application of the cutting condition decision system to a mold company.
