This paper proposes the development of a tuning methodology which can set proper values Computer Numerical Control (CNC) parameters to achieve required machining performance. For conventional operators machine tools, CNC were hard be adjusted optimal settings, was complicated and time-consuming task. To save time in finding parameters, objective this research develop practical tune effectively for easy implementation commercial controller. Firstly, effect controller on tool-path planning...

Processing machines require various sensors for process monitoring and control to improve processing accuracy.Sensors become a critical factor in both automated production intelligent manufacturing.It is interesting that the accuracy of microdistance-measurement device affects fine-tuning quality cutting tools.In this work, we developed noncontact microdistance sensor based on giant magnetoresistance (GMR) effect by combining neodymium magnet with tool slider.The slider displaceable along...

This paper proposes the machining time optimization and surface quality improvement based on a digital twin model of machine tools. considers servo loops, feed drive system, tool center point (TCP) effects which were constructed simultaneously. The frequency response actual was excited by swept sinusoidal waveform then identified. Finally, parameters controller tuned to achieve optimizing decrease oscillation TCP.

In this study, we constructed the mechatronic model of a tool center point (TCP-MM) present in virtual environment.Since dynamic behavior TCP affects productivity, geometric accuracy, and surface quality machining parts, TCP-MM can evaluate behaviors motion trajectory.The machine tools consists servo feed drive inside loop structure with outside loop.Firstly, developed position measurement equipment that collects relative displacement between workpiece.Subsequently, frequency response actual...

This study proposes a 2D contour measurement system at the tool center point (TCP) that consists of Blu-ray pickup head and position sensitive detector (PSD). The TCP displacement is equivalent to relative between workpiece. When machine tools operate part along desired contour, affects machining geometric accuracy. To evaluate displacement, errors are measured by cross-grid encoder (KGM) in practice. However, it difficult install KGM as large expensive. In this study, an optical (OMS)...
