12/5/2023 0 Comments Form tapsyou can't verify stock removal properly in CAM simulation. On my current part I have like 28 chamfers other than M12 holes. But with this, I have to exclude threaded holes and pickup all other edges one by one. My usual workflow is pickup top face and add 0.25mm or 0.5mm chamfer or fillet. I usually like to add chamfers and fillets at the very end. But yes, if I machine it using the tools I intend to use they will come out looking same.ģ. In this specific case the chamfers on the M12 holes look bigger than all other chamfers visually which is again not something I prefer. I wouldn't want such discrepancies in my workflow.Ģ. In my case (as mentioned above) the hole size needs to be 11.3 mm but its 10.274mm in the model. For starters the geometry of your 3D model is different than your actual part. This method screws up a lot of other things though.ġ. Yup that fixes my issue with manufacturing. Is there already a solution that I don't know about or this feature is missing from the software?īasically hole feature should allow us to choose diameter of the hole for threaded holes which is greyed out as of now. I create paths and output direct to the machine and measure right away. Since I machine my own parts I rarely create drawings of my CAM work. Problem with this method is that you loose the documentation as to what holes are threaded and what whole are regular. My fix was to create those holes as simple holes with size equal to the pre tap drills. No wonder why there were no visible chamfers. I had 0.5mm chamfer on top of this hole which made the upper dimension of the chamfer came out to be 11.274mm.įor M12 x 1.75 forming tap, recommended drill size is 11.3mm. In case of M12, the actual hole created was 10.274mm. Some investigation later, I found when I created threaded hole the size of the hole is a predetermined value. After machining I found the chamfers on the M12 holes were missing. Have a cutting or turning question?

A rolled thread is more precise and consistent than a cut thread, eliminating the need to closely monitor thread making production. Why Should you be Thread Rolling? See Our Video Below!ĭo you want to thread roll 12 parts in the same time that it takes to do one single point threading? See our video where 12 threads are completely rolled in the same time it takes to make one pass with a single point tool.
