Abstract

The CNC machining technology is of great significance to the modern manufacturing industry. In this paper, the motion of the CNC machining tool is optimized. In order to solve this problem, we divided into steps as follows: firstly, we take a look ahead velocity curve and deceleration control algorithm and interpolation algorithm based on multi cycle in speed control. The optimization model is established in which taking the establishment of the processing time as the objective function, taking the interpolation velocity as the decision variable, and satisfying the error requirements .Then, the influence of the cutting tool"s radius on the angle between the patch and the two adjacent straight line is analyzed, and the working efficiency is affected by the change of the machining time under the condition of equal arc length. Study found that the greater the radius of the arc, the smaller the curvature, and the speed is relatively high after the inflection point. In addition, considering the influence of the instantaneous starting acceleration and the instantaneous starting speed on the model, the initial velocity is not zero and the minimum speed limit exists in the whole process. Finally, we using the Simulink component of MATLAB to model the processing line for the case of line and arc, which further confirms the accuracy of our model.
