RISImproving Contouring Accuracy of NC/CNC Systems With Additional Velocity Feed Forward Loop
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: One of the factors which affects the contouring accuracy of multi-axis NC/CNC contouring systems is axes mismatch which means that the time constants and the open-loop gains of the machine ...
Real-Time Estimation of Cutting Process Parameters in Turning
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A simple method for real-time estimation of the parameters which characterize the relation between cutting force and feed in turning is described. The method produces very accurate results which ...
Reference-Word Circular Interpolators for CNC Systems
Publisher: The American Society of Mechanical Engineers (ASME)
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 ...
Stability Analysis of a Constant Force Adaptive Control System for Turning
Publisher: The American Society of Mechanical Engineers (ASME)
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 ...
Reference-Pulse Circular Interpolators for CNC Systems
Publisher: The American Society of Mechanical Engineers (ASME)
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 ...
