Adaptive force control in turning have been realized to perform autonomous and intelligent machining. An adaptive force control module have been developed on Digital Signal Processor(DSP), and built in a Personal Computer(PC). Feed speed is controlled to keep cutting force constant by the adaptive force control module. Furthermore, cutter location is instructed in real time by a tool path generation module. The retrofitted NC lathe does not need an NC program which instructs cutting parameters for the machining, because it is controlled by both the adaptive force control module and the tool path generation module. In the experimental cutting, a depth of cut can be reduced in a moment by the event corresponding to the chatter detection. It shows that the ability and flexibility of autonomous machining to unexpected cutting conditions such as chatter vibration.By integrating additional monitoring functions, autonomous and intelligent machining will be performed.
