Abstract

The adaptive control system of milling on the CNC machine is presents. The system is designed to stabilize cutting power when conditions change milling of complex surfaces. The structure of the system consists of a control module, a feedback module and the module of generation of a control signal. Feedback module connected to the CNC via RS232 interface, and the module of generation of a control signal is connected through a dedicated hardware block to the encoder manual correction of feed rate. The experiments using a specially created digital models of the milling process allowed us to eliminate the hazards and to conduct research in a wide range of change of parameters up to the loss of stability of the system. Performed experimental studies to determine the feed rate control channel, which ensures the stable operation of the system. The possibility of stabilization of the cutting power due to the automatic feed control was confirmed.
