UG 后处理优化：支持发那科/三菱/AB 系统及 3+2 坐标转换
本文分享一款适用于 UG 软件的高效后处理程序，兼容发那科、三菱及 AB 系统。该版本经过深度优化，专注于解决多轴加工中的坐标计算与程序规范问题，旨在提升编程效率与加工安全性。
核心功能特性
- 智能坐标计算：支持任意角度自动计算，完美适配 3+2 定轴加工模式。
- 开放源代码：程序未加密，方便用户根据实际需求进行二次开发与调整。
- 信息可视化：程序头自动生成刀具列表；换刀时清晰显示刀具侧壁及底面余量。
- 指令优化：同把刀具转换角度时自动输出 G43 指令；钢性攻丝循环自动调用 M29 指令。
优化后程序格式示例
以下为该后处理生成的标准 NC 代码片段，展示了程序头信息、刀具列表注释以及多轴联动加工的指令逻辑。
