In order to make industrial robots and computer numerical control (CNC) machine tools perform tasks efficiently, many techniques for the acceleration and deceleration of industrial robots and CNC machine tools have been proposed. Polynomial technique can generate velocity profiles of various acceleration and deceleration characteristics, but it requires a lot of computations. Digital convolution technique can generate efficiently velocity profiles, but it cannot generate velocity profiles with some kinds of acceleration and deceleration characteristics. This paper proposes an efficient approach for generating velocity profiles that cannot be generated by previous techniques as well as velocity profiles generated by them. Based on the proposed approach, an acceleration and deceleration circuit for industrial robots and CNC machine tools is designed by using the VHDL and it is implemented with a FPGA. A velocity profile generated by the acceleration and deceleration circuit will be applied to one single-axis control system. 相似文献

Cross-coupled fuzzy logic control for multiaxis machine tools 总被引:1,自引:0,他引:1
This paper presents a design and implementation case study that focuses on contour control of a biaxial CNC machine tools. Since, it is difficult to obtain an accurate nonlinear mathematical model of cross-coupled multiaxis machine tools, here we investigate an alternative to conventional approaches where we employ crosscoupled fuzzy logic controllers for improving the contouring accuracy of multiaxis CNC machine tools. A new fuzzy rule-generated method which is based on a performance index of the contour error obtained from an on-line estimation algorithm is proposed. An adapted output scale factor is adopted to improve the system performance. Experimental results have shown that the desired contouring accuracy can be achieved, and the proposed approach outperforms over uncoupled approaches. In conventional control, increasing contour feedrate for productivity may result in larger contour errors. However, the experimental results have shown that the performance of the proposed approach is still quite good with increasing contour feedrate. 相似文献

Cutting force control of milling machine 总被引:2,自引:0,他引:2
In metal cutting processes, an effective control system, which depends on a suitably developed scheme or set of algorithms can maintain machine tools in good condition. In this paper, an approach is developed for cutting force control of CNC machine. Several linear models are identified based on different working conditions. A dominant model plus uncertain terms is derived from these model set, to yield the necessary and key information from the system. Subsequently, it is used as a state estimator, and robust control is carried out by using the observed variables and cutting force. The developed approach is applied to a milling machine center. Examples taken from experimental tests shown that the developed approach is effective for the uncertain CNC machine. 相似文献
