Abstract: A supervisory process control approach to machining is presented in this paper, and demonstrated by application to a drilling operation. The supervisory process control concept incorporates ...

Abstract: A statistical analysis of hole quality in drilling was performed. Using standard twist drills, holes were drilled dry in hot rolled steel. The effects of feed and speed on the hole quality ...

Abstract: The design and implementation of feed, speed, and torque controllers for drilling is discussed. Dynamic models of the feedrate drive and spindle motors were developed using experimental data and ...
