Thread milling: Define the thread by value? (Improvement suggestion post)

[produktion2PZ3GF]

Hi, this is an suggestion for a change to the thread mill toolpath. (Didn't find a good place to upload suggestions)

Defining the thread is done with "pitch diameter offset". I suggest an option to define the thread by an diameter. Just as in helical you can change from Angle to a value.

You could then choose the hole for the location and then for a M12 thread you'd type "12mm".

I often get models that have different drill sizes, I even had a model now that had the same Thread at several locations around the part but it had different drill sizes. 

With this function you can Template your thread-mill operations without having to worry that the pitch diameter needs to be adjusted. Something I find useful since I find thread-milling to be a bit time consuming before you get the first thread right.

I agree, this is same as the Diameter Over ride I suggested last week for the Bore cycle. Mcam also just allows you to enter the desired "cut" diameter and ignore the actual cylinder size.

This has been discussed in length for quite a while but there have been no improvements.. Even calling it "Pitch diameter offset" is misleading as this value has nothing to do with the pitch diameter. Even more cumbersome doing it this way as the model needs to have the correct minor which is fine if we draw it but gets to be a pain with customer supplied models if they aren't correct. Would be AMAZING if we could have a drop-down to select common thread sizes and Fusion would populate the correct values. Coming from FeatureCam, I miss that feature for sure.

Smart idea! Especially since we know they already have a thread list function available in the hole/thread tool!

Yes lets get this in an update. Would be a very nice improvement. A spot to define a taper for npt would be huge to. Most softwares do not put the correct hole size in for npt taps on the design side. The ability to override a diameter and add a taper angle to threadmilling would be huge improvement.

This would be soo good, I imagine the majority of people using Fusion Cam(Would be interesting to know what percentage) are machining customer supplied models where, as others have mentioned often have incorrect hole diameters and there is no thread data to extract from those holes anyway.

If they are modeled in Fusion you can use the new "auto" hole parameters to drive the Thread milling/turning toolpaths directly from the model.

Something like this:

Not useful for me as I'm almost 100% imported .sldprt files.

Even our 20+ year old Fagor lathe control has a list of all sorts of thread types you can pick and it populates all the data

I recommend you change  the Thread pitch expression to "Tool_threadPitch" 

would also be cool to see it as 1/20 or 1:14 instead of the actual decimal values, but that may just be me.

I already have that as my default. But as you say, it doesn't really show.
