Abstract: A model of the flank wear of cutting tools is developed by using linear control theory. The flank wear is assumed to consist of a mechanically activated and a thermally activated component. ...

Abstract: An analysis is presented of computerized numerical control (CNC) for manufacturing systems. Two types of CNC systems referred to as Reference-Pulse and Sampled-Data are discussed. In the first ...

Abstract: Biaxial control systems for generating predetermined paths under load disturbances, such as encountered in NC and CNC systems for machine tools, are conventionally designed such that the control ...

Abstract: An optimal locus concept is introduced as the basis for an optimization methodology for real-time control subject to time-varying constraints. The optimal locus in the control plane contains all ...

Abstract: The workload in Air Traffic Control Centers often prohibits the controllers from making lengthy observations of the moving pointer indicators in order to obtain sufficiently representative estimates of the current surface ...

Abstract: The principal control structure of CNC machine tools and industrial robots is similar, since in both systems each axis of motion is separately controlled with a position feedback loop. Nevertheless, ...

Abstract: Interpolation techniques for CNC manufacturing systems are either of the Reference-Pulse or Reference-Word type. Reference-Pulse interpolators have been discussed in a previous paper [2]. The present ...

Abstract: Adaptive Control Constrains (ACC) as applied to machine tool systems refers to the regulation of the cutting process characteristics such as spindle power, cutting force etc., by varying the ...

Abstract: Interpolation techniques for CNC manufacturing systems are either of the Reference-Pulse or Reference-Word type. Reference-Pulse interpolations emit a sequence of pulses as reference signals to the ...
