Chamfer Holes

[cunder]

Let say there are several different size arcs at "Z" zero plane, or at least all on one plane. I want a .015" chamfer on each size. I want to just plunge a 45° tool. Is there a way to select all holes and use some type off inceremental function to create the chamfers?

 

 

 

Regards.

Arcs as in a contour? Sounds like you mean holes since you mention plunging a tool. If they're all in the same plane, I would create an OP for each hole diameter, since the plunge depth will be different for each Ø. How but just chain>contour>chamfer that will get all of them in one op.

No there is currently no way to pick all the arcs and chamfer them in one operation. Feature Based Machining would be required to accomplish this. You'll have to do as Mic6 says and create individual ops for each arc.

 

IF the software could "look"/analyze a solid model or wireframe model and create the appropriate operation/pick the tool/and post the program then a 6 yr old could do it and you would be out of a job.

Instead of plunging a 45 deg tool to create the chamfer why not contour the chamfers instead, use incremental z depth and use an entry/exit that will accomodate the smallest hole.

You can use "change at point" to set a different depth for each hole.

Auto Drill will do exactly what you are asking for. There is a setting to chamfer with a spot drill. Put in the size of the chamfer you want and mastercam will adjust the depth to maintain the size.

I put points in the center of the holes at the depth I need to create the different size chamfers, then use incremental depth. Works like a champ.

[gcode]

you can do this with one op but it will take some work.

figure out the Z value each hole will require to get the desired edge break

draw a point on the C/L of each hole and the proper Z level

select the points

Use a G81/G82 drill cycle with

Retract set ti incremental .1

Top of stock set to the Absolute value of top of stock

depth will be incremental Z0

this works well with Fanuc controls but some controls can't handle multiple depths in one canned cycle.
