Center drills are locked at 60Deg???

Center drills are locked at 60Deg???

Anonymous
No aplicable

I have a bunch of 82-degree and 90-degree center drills in our tool crib that I need to use fairly often to spot drill and countersink at the same time. I'm trying to use a #3-82Deg center drill and just realized that FC locks all center drills to 60Deg at the body and 118Deg at the tip?! Are you kidding?

 

Has anyone involved with developing this software ever actually programmed a part or worked in a machine shop? I know center drills other than 60Deg are not the norm, but they exist and are still used pretty often for various purposes. I guess I'll just hand program this one...

I haven't dealt with that issue, so I don't know if this would be a reasonable solution.  How about selecting pilot drill rather than center drill in the strategy?  That way you could use a curve to define the tool.  You would likely need to enter the drill depth, but that wouldn't be difficult.

Besides drawing a curve for a new tool, I cannot think of any way to solve this problem. And that may take too much time if you change center drill sizes on a regular basis. 

 

You would think they could just open up the angle field so that you could choose the angle. I think all the other information  already has to be enter. (Body diameter, tip diameter, tip length, etc).

Try going to your center drill properties and changing it to a spot drill, then you can change your angle on your tool. Hope that helps.

This will figure incorrect depth when attempting to spot and countersink the hole in one operation. Aclark will still have to hand determine his depth to get the correct countersink size.

That only sets the tip angle.  It won't set the second angle, since the spot drill definition doesn't have one. It only allows one diameter.

That is correct. I wasn't considering the second angle. I'm used to using just a 90 degree spot for all my spotting and chamfering.

Make a custom form tool. That would solve the problem.

OK,

 

So, next problem...related to the first. Lets say I'm using a drill-mill to spot a hole, chamfer an edge, and side-mill around a thru-profile. Naturally, I want all of this to happen under the same block of code (all within the same tool change). I can't use any tool from one feature to machine any of the others, since those tool types are not allowed in other places. I can't side mill with a chamfer tool or spot drill, for example. Not all features lend themselves well to using the built in "chamfer" feature and so I have to use Side Milling a lot to produce edge breaks and chamfers. So, the workaround has been to create tools in each category that mimic the tool I want, then re-number them all to the same tool number. FeatureCAM still outputs them each with their own tool change since it still sees them as different tools. The way I see it, if I want to drill a hole with a face mill I should be able to do it! Has anyone found a workaround for this problem?
