摘要
针对普通旋转锉制造工艺与应用中的刀齿汇交于刀具顶点,造成容屑空间小、切削条件差等问题,提出了一种分区型旋转锉加工算法,在齿底轮廓面上进行分区型刀刃曲线的规划,并通过小圆心角、斜平面等参数,实现对旋转锉外形轮廓与刃形的有效控制.为适应旋转锉加工机床结构多样化、复杂化的发展趋势,解决用户数控加工后置处理过程灵活定制的问题,借鉴机构运动学方法,采用旋转变换矩阵,实现对机床结构统一化建模,并运用逆运动学方法,完成旋转锉加工的通用后置处理过程.刃磨实验验证了所提出的加工算法的正确性,能够满足实际使用要求.
For the deficiencies, such as cutter teeth converging at the vertex, which means small chip space and poor cutting condition, in the manufacturing process and application of ordinary rotary burrs, a partition type rotary bur processing algorithm was proposed, that edge curves were planned in the tooth bottom contour surface. Through some parameters, such as the small central angle and the oblique plane, it took contour and edge shape {or rotary burrs under effective control. At the same time, to custom post-processing procedure, drawing on the methods of mechanism kinematics and ro- tation matrix, unified models for machine structure were established. And based on the inverse kine- matics method, the generic post-process for rotary bur processing machine was realized. Experimental results demonstrate the effectiveness of the proposed algorithm.
