请问楼主：你链接中的文档中说，在执行NC ROUTE这项功能时，必须加一个设定档{ncroutebits.txt)，不知写文中的内容时必须遵循什么原则否？铣刀都有哪些尺寸？

该文件需自建，简单地按如下格式即可：' l4 F' n" a+ O8 R O/ J% l3 q

When NC Route routes oval and rectangle slot holes, an appropriate tool is chosen from ncroutebits.txt using the following guidelines: s* J4 b; Q! V3 h2 x0 h" n! R
- Rectangle Slot: a tool size smaller than the minimum dimension of the rectangle must exist to route a rectangle path with appropriate Excellon tool compensation.
- Oval Slot: a tool size that exactly matches the minor dimension of the oval must exist to route the oval as a single line path. Otherwise, a tool size smaller than the minor dimension must exist to route an oval path with appropriate Excellon tool compensation.
