Improve thread milling capabilities

Improve thread milling capabilities

Hi everyone,

 

I'm a bit stuck in the thread milling capabilities within Fusion. I've already asked in the CAM section for help, but there doesn't seem to be a solution ready. (http://forums.autodesk.com/t5/computer-aided-machining-cam/drill-point-thread-mill-programming/m-p/6...)

 

When thread milling, fusion is always looking at the diameter of the modeled hole, and an offset is possible. This however isn't working well when sometimes holes are sized differently. An m10 hole can be 8.5 mm (standard drill size) or 8.376 mm (the minor diameter) or simply 10 mm.

 

What i would really like some more control over how a hole should be thread milled.

Regardless of the hole size, or even a point should be enough to thread mill.

 

We need a few things:

  • D (Major diameter) 
  • d (minor diameter)
  • Depth
  • Pitch
  • Angle (for tapered threads)
  • Climb/conventional milling
  • Type of radius compensation
  • Type of feedrate (toolcenter or outside of tool)
  • How many teeth a tool has
  • Spring passes (with or without finishing offset)
  • possibility to use different kinds of thread mills (multiple threads, drill-thread mill, indexed mill etc.)

 

 

 

 

The use of the cutter in this video would be great, 4 seconds for a completed M10 hole!

I support the list of features above.

 

Specifically I am looking to be able to have multiple "Repeat Passes", with really long thread mills there is enough deflection that a single spring pass isn't always enough. Being able to enter in how many spring passes I'd like would be great.

A good start would be to clearify the term "pitch diameter offset".
As far as I know the definition of PD is NOT simply major-minor (or drillsize)

It would be easier if the software did the (rather simple) math for us
like: I got a tool with diameter D, and a hole with diameter d and I want a thread of diameter X
