[Ad...] Posted May 19, 2020 Share Posted May 19, 2020 Hey guys, I have a call out for a C'Sink Diameter on a Cylinder. Which formula or method I would use to get the .345 to .355 Diameter. See Attached. Thanks..345-.355.png Link to comment https://qualityforum.zeiss.com/topic/12194-cone-diameter-on-cylinder/ Share on other sites More sharing options...
[An...] Posted May 20, 2020 Share Posted May 20, 2020 Have you tried a "cut" of the cone and cylinder? Link to comment https://qualityforum.zeiss.com/topic/12194-cone-diameter-on-cylinder/#findComment-60974 Share on other sites More sharing options...
[Ro...] Posted May 20, 2020 Share Posted May 20, 2020 Im not sure what you mean by "CSink Diameter on a Cylinder", is it a cylinder or a cone? Either way i would get a Csink diameter by making an intersection between a cone (shell) and a plane.

Then, using the cone calculation on the plane. So, let's assume cylinder is .750 dia and the view shown is facing +Z. Create a plane feature. Go to Options and select Theoretical Feature. Enter .375 in the Z Nominal field. Right- click in the Z Actual field and select Formula. In the middle column, locate the cylinder and in the right column, locate the radius. Double-click on the radius item and it will put the formula to extract the actual radius of the cylinder and use it as the actual Z value of the plane.

[An...] Posted May 20, 2020 Share Posted May 20, 2020 on the drawing it looks like a cylindrical sink, but I suspect that it is a conical sink. But it should be drawn elliptically.

[Ad...] Posted May 20, 2020 Author Share Posted May 20, 2020 It is an old drawing, they are even missing some features such as the diameter for the thru hole but it is an old print.

[Ad...] Posted May 20, 2020 Author Share Posted May 20, 2020 Hey Tom, I did the method you mentioned and it worked, but what I did was on the Y -1.375 and for Z -.390. Then I applied the Cone Addition with the the cone to the theoretical plane and gave me the correct measurement. Thanks Tom.

[Ad...] Posted May 20, 2020 Author Share Posted May 20, 2020 Hey Robert, I used to, but now I am at Eaton. I have been working at Eaton since 2018. How have you been Robert, when i saw your name I wasn't sure if it was you or not that used to work at Deltron then to RTC for a bit.

[Me...] Posted May 20, 2020 Share Posted May 20, 2020 Hey Adrian, Good to hear from you. Hope Eaton is treating you well. You finish school? You still with your lady? Small world out there. Hope you're staying safe during all this pandemic stuff. Lots of really smart people on this forum so you're at the right place. Lots of fun trying to measure a CS on a tube, huh? Glad you got it figured out. Stay safe, Robert Link to comment https://qualityforum.zeiss.com/topic/12194-cone-diameter-on-cylinder/#findComment-60996 Share on other sites More sharing options...
[Ad...] Posted May 20, 2020 Author Share Posted May 20, 2020 Yeah, I finished but I might go back to get an MBA or Master's in Information Studies. Not sure yet. Yeah, we are still together and we are married now. Yeah we are staying safe, and hope your family is doing good and staying safe as well. This forum is a great resource for to learn new things, and programming.

I suppose Calypso could do it with some fancy formulas. In a pinch, placing a go or no-go gage pin would suffice.Screenshot 2021-08-13 094911.jpg Link to comment https://qualityforum.zeiss.com/topic/12194-cone-diameter-on-cylinder/#findComment-61004 Share on other sites More sharing options...

"4.5.13 Chamfered and Countersunk Holes on Curved Surfaces Where a hole is chamfered or countersunk on a curved surface, the diameter specified applies at the minor diameter of the chamfer or countersink.

[Ma...] Posted August 18, 2021 Share Posted August 18, 2021 I totaly agree with Andreas. When i would measure this with manual caliper i would measure the widest diameter because it will tell me how deep i am and it's comparable to measuring on straight plane.

I believe this is specified this way by default for countersinking fasteners. By specifying the minor diameter, you can use the same countersink diameter as on a flat surface and still know that the entire fastener is below the curved surface.

If you measure the widest diameter of the countersink on an OD, the head of the screw will protrude beyond the OD. The drawing is specifying the diameter of the countersink, not the depth.
