I just figured out how to c'sink!!!!!!

[Mr. Wizzard]

I'm kind retarded and do things the hard way without knowing it for a while.

 

I just figure out you can use to depth calculator in the drilling page to have it figure out the depth needed for a .510 x 82 c'sink!!

 

As long as the tool is defined properly, diam, flat, angle, you just type in the desired diameter and BAM, magic!!!!!!

 

Takes the guess work out, i hope, as long as it comes outa the machine correct.

82° = .5755 x dia

90° = .5 x dia

120° = .2866 x dia

As long as the tool is defined properly, diam, flat, angle,

The flat at the bottom MUST be defined correctly. I usually program a test hole where the c'sink would come out .1 undersized or something. To ensure your getting what you want before its to late. We have a shadowgraph type tool setter. I will tell the operators to set the tool length offset where the angle meets the OD of the tool, this eliminates most of the error.

for faster and more precise c'sink , i still prefer blend toolpath and a ball mill for flathead over 1/2

I just do a simple calculation within the depth dialog (for a 90 degree countersink). (Diameter of Countersink - Diameter of Tip Flat) / 2)*-1 gives me the correct Z coordinate. It works everytime

C'mon guy's... you are bursting Mr. Wizzard's bubble... he found a new toy in Mastercam and came here to brag and all you can do is talk about the different ways to do it

 

GO MR. WIZZARD!!!

i'll be excited when I figure out exactly how the 3d champher works. ;p

Use a ballnose cutter to create a 3d chamfer on an edge that does not lie flat in your tool plane.

That is the way that I usually do it. Ive just always been curious what situation called for contour 3d champher.

I've used it for chamfering holes in round surfaces (tubing) and other non-flat surfaces. You can get it to work, but it's confusing when adjusting the depth.

 

As for the c'sinking, I've used JP's method before, but when tool tip diameters change, so must your calculations. I finally figure out you just punch the tool specifics in the drill calculator in Mastercam and it figures it out for you. Woo Hoo!!!!

+1 that's what I do.....no guess work.
