零件连成一片切,只下一次刀
Link the parts and plunge once
挨着的零件在离得最近的地方搭一座"桥",整片零件连成一条路线。整片只下一次刀,分几层切时层与层之间也不抬刀。不在废料上空走,隔着大块废料的另起一段。
- 每块零件都是顺铣,边口质量和单独切一样
- 桥口前后各重叠 2 mm,两块零件的边在桥口都不留接刀痕
- 小件可以单独先切(多留皮、降速),也可以一起进链
- 出刀路前逐条核对:刀扫过的地方不碰任何零件
- 另有共边切法:相邻两块共用一刀,缝只切一遍
Neighbouring parts are joined by a short bridge where they sit closest, so a whole group becomes one continuous path. One plunge for the group, and no lifting between depth passes. The tool never travels over open scrap; parts separated by a large offcut start a new path.
- Every part is climb-cut, so edge quality matches cutting it on its own
- Bridges overlap 2 mm at each end, leaving no witness marks on either part
- Small parts can be cut first on their own (extra onion skin, slower feed) or join the chain
- Every path is checked before NC is written: the tool never touches another part
- Common-line cutting is also available: neighbouring parts share one cut
