Energy Saving Algorithms for Cooling Systems in Machine Tools

Autor: Sungchul Jee, Taeho Kim, Taejung Kim

Publikováno v: Journal of the Korean Society for Precision Engineering. 32:345-351

Machine tools usually consume more energy in cooling systems than in spindle motors. This is largely because circulation pumps in the cooling systems are continuously powered to measure the temperature of spindle motors. In this paper, energy saving

Standby Strategies for Energy Saving in Peripheral Equipment of Machine Tools

Autor: Taeho Kim, Sungchul Jee, Taejung Kim

Publikováno v: Journal of the Korean Society for Precision Engineering. 30:486-492

Energy cost has been increasing rapidly to comply with environmental regulations worldwide and the manufacturing industry who consumes more than half of the total energy needs to improve their cost competitiveness considering environmental costs. Mac

Real-time inertia compensation for multi-axis CNC machine tools

Autor: Jungseung Lee, Sungchul Jee

Publikováno v: International Journal of Precision Engineering and Manufacturing. 13:1655-1659

Variation of the effective moment of inertia due to load disturbance in a CNC feed drive system may increase control error for each axis of motion and thereby degrading total precision including contouring accuracy. Although some investigations have

Adaptive fuzzy logic controller for feed drives of a CNC machine tool

Autor: Yoram Koren, Sungchul Jee

Publikováno v: Mechatronics. 14:299-326

This paper introduces an adaptive fuzzy logic controller (AFLC) for precision contour machining which adjusts both input and output membership functions simultaneously. The parameters of the proposed controller are self-tuned in real-time according t

Integrated NURBS Surface Interpolator Considering Both Rough and Finish Cuts

Autor: Tae-Hoon Koo, Sungchul Jee

Publikováno v: Transactions of the Korean Society of Mechanical Engineers A. 27:1958-1966

Three-axis CNC surface machining entails a series of processes including rough cutting, intermediate cutting and finish cutting for a reference surface defined in CAD/CAM. This study is targeting development of an integrated NURBS surface interpolato
