Abstract: Optimization is an important way to improve the machining quality, efficiency, security and safety. In traditional way, feed rate is specified off-line in CAM system by process planner, which leads to the low machining efficiency. In the paper feed rate optimization technique based on generalized predictive control is researched. The open architecture is adopted to develop an adaptive controller, where the feed rate can be real-time adjusted in CNC system according to the measured cutting force. An open CNC controller with the function of feed rate optimization is implemented, which consists of a series of software modules. Simulation experiment has been finished to prove the proposed method.

Abstract: Filament tension control system is integrated into real-time core of open-architecture winding CNC. Based on filament tension generation theory for filament wound component, the method of process elimination is applied to modify the theory of filament tension control to transform uncontrollable elastic tension to known quantity, thus improves the control precision of tension in filament composite wound components.
