Chamfering

[GREG]

Any tips on chamfering.

The components we manufacture have to be totally

deburred , and chamfering at various levels up to vertical walls ( without hitting them ) currently

is a time consuming process to program.

I am currently creating geometry away from vertical walls and then contouring. As there can be 100s of walls to aviod doing this is as much fun as watching paint dry.

Is there an easyer way.

Now have you tried using contour chamfer at all use say a carbide spot drill?

Makes for some great chamfers.

This way you can use the existing geo.

You might have to break a line or two.

But you should not have created all new offset geo.

In nine of course this will be a little easer with Dynamic chain so you can stop it any were along a chain.

May be I wasn"t to clear.

We use modifyed carbide chamfering tools - dia 6mm with 0.5mmx0.5mm 45deg edge. Is there a way of chamfering up to a vertical wall (edge of a multi level pocket)without creating boundary geometry.

Somthing like check surfaces but for 2d geometry.

For that I break the contour usally half the dia of the tool from the wall.

So this a good qustion i will have to try some thinks or wait and see if some one eles has a good answer.

Sorry.

Greg,

 

With version 9.1 (if you have it) you can use the "adjust start of contour" and "adjust end of contour" section of the Lead In/Out dialog in most toolpaths to shorten your toolpath by your tool radius.

Now that is cool.......one more reason to get 9.1.

That is the way to go...I Use this option constantly.

Keep in mind that in 9.1 (dont know about 9.2) the extend option creates a linear extension even if the drive geometry is an arc. So be careful on ID's. Otherwise a great feature.

+1 on adjust length of contour.

 

I have to hold a .001 to .004 chamfer on some microwave housings that I didn't build

 

I use carbide and shorten the length by 55% of the cutter.

We also do alot of chamfering with a ball endmill and a surface/solid face. This allows you to pick check surfaces. This is a great function for different angles ect. Makes for a little longer path sometimes. But better that ordering special cutters ect.
