| 摘 要： | 马鞍型曲线焊接在工业生产中使用广泛,目前常用的插补算法不能适用于其自动焊接.基于三菱PLC控制器Q02HCPU,通过对插补算法设计原则的研究,在马鞍型空间几何特性基础上,提出了基于逐点比较和角度逼近的直接插补算法,并通过MATLAB软件进行仿真实验.实验表明,该算法插补精度高,软件编程易于实现,提高了马鞍型焊接生产的自动化程度.

| Abstract: | Saddle shaped curve in the industrial production is widely used in the welding, and the traditional interpolation algorithms cannot be applied to the automatic welding. In this paper, based on the Mitsubishi PLC controller Q02HCPU and the interpolation algorithm principle of design research, the saddle-shaped geometry characteristic foundation, proposed based on point by point comparison and angle approximation of direct interpolation algorithm, and through MATLAB software simulation. The experimental results show that the algorithm has high precision in interpolation, and make software programming easily to realize, to improve the saddle shaped welding production automation. |
