CAM Programming Tips: Thread Turning Sandvik Coromant

Welcome to the Thread Turning CAM tip from our CAM Programming Tip Series. Thread Turning is an established and widely used threading technique for the threading of parts. We hope you find this video tip helpful to your thread turning processes for application in a variety of industries. VIDEO TRANSCRIPT: Thread Turning is an established and widely used threading technique for the threading of parts. It is commonly the 'first choice' technique for threading rotational parts because of it's high productivity and surface finish compared to other techniques shown here. (zoom in on thread turning pic in slide) With thread turning there are 3 primary programming infeed methods: Modified Flank Infeed, Incremental Infeed (also known as Alternating Flank Infeed or Zig-Zag Infeed), and Radial Infeed. With Modified Flank Infeed the insert is fed in at the angle relative to the thread profile. This angle is usually 1 to 5 degrees 3-5degrees for 'A' and 'F' insert Geometries and 1degree for chip breaker 'C' geometries. The advantage of this method is less heat generated, less vibration, and higher production reliability. This method should be a 'first choice' for most threading operations. With Incremental infeed the insert is fed in at the angle of the thread profile, but here each leading flank pass is alternated with a trailing flank pass. The result is more even insert wear and longer tool life. Making this the ideal choice for larger thread profiles. With Radial Infeed the ...
