DFMXpress turn-rules

Are you striving to solve your Quality Issues upfront @ the Design Stage?



SOLIDWORKS 3D CAD provides a 3D workspace which showcases your final results before getting it for production.

As a part of DFMXpress, the analysis tool which helps in upstream validation of difficult areas of manufacturing, following are the set of turn-rules based checks. 

Sequencing with our earlier posts, following are the turn-rules:

TURN RULES

1. MINIMUM CORNER RADII FOR TURNED PARTS
  • Avoid sharp inside corners. Provide a generous inside radius to accommodate a tool with a large nose radius, which is less prone to breakage

  • A turn-down surface perpendicular to an un-machined (cast) surface might cause burrs

2. BORE RELIEF FOR TURNED PARTS:
  • Provide tool relief for the bottoms of blind bored holes in turning operations.
