FANUC系统常用的插补功能有直线和圆弧插补,由这两种指令构成了常规的刀具轨迹,而直线和圆弧的组合轨迹除了切线组合外,其他组合都会引起急拐急停现象,对于常规加工问题不大,但对于高速进给切削,就受到了一定的限制,不仅影响刀具的切削性能和使用寿命,还影响加工效率和切削精度。此外,FANUC基于圆弧插补和Z轴的直线插补合成的螺旋插补则更进一步增强了系统的功能,但对于XY平面内的螺旋插补功能部分系统尚不支持,本文基于FANUC系统开发XY平面内螺旋渐开线刀路轨迹,避免了急走急停,保证刀路衔接的顺滑过渡,实现高速切削,也为系统的功能开发进行了探索。
FANUC system commonly used interpolation function has a straight line and circular interpolation, the two commands constitute a conventional tool path, and the combination of straight line and arc trajectory in addition to the combination of tangent, the combination of other will lead to emergency stop emergency phenomenon, For the conventional processing is not a big problem, but for high-speed feed cutting, it is subject to certain restrictions, not only affect the cutting tool performance and service life, but also affect the processing efficiency and cutting accuracy. In addition, the FANUC spiral interpolation based on the circular interpolation and Z-axis linear interpolation synthesis further enhances the function of the system. However, the system of spiral interpolation in the XY plane is not supported yet. Based on the FANUC system development XY plane spiral involute path, to avoid the urgent emergency stop, to ensure a smooth transition path convergence, to achieve high-speed cutting, but also for the system’s functional development has been explored.
