cutter comp on a toolpath driving tool center

[woody123]

I would like to output cutter comp on a 2d or 3d toolpath driving tool center on the geometry.

An option like "compensation type: off w/comp"

 

I sometimes want to drive the cutter center and still output a G41/G42.

in control

[woody123]

That doesn't drive the center of the cutter on the geometry.

I want a toolpath just like compensation type: off

but with a G41 in the code.

set your tool diameter to 0

[woody123]

I see that you can use change at point but it doesn't work for a 3d toolpath.

 

I recon this is more of a request than a question.

[shazam/TPP]

use wear

[Derek Rozon Armatec]

I agree with Terry...Using the Control Comp option works for both 2d and 3d contours. It drives the cutter on center and adds the G41 D(tool #) on all contours. What exactly are you tring to do?

use Wear

 

All I use and all I'm gonna use

From the help in Mastercam 2D contour

quote:

Wear - When this option is selected, Mastercam calculates the compensated tool positions just as if Computer was selected, but also outputs the G41/G42 codes. This lets the operator adjust for tool wear at the control. Enter the difference between the selected tool size and the reground tool size at the control as a negative number

I think that were is what you want to use as long as your post is setup to use cuttercomp correctly.

Wear offsets the toolpath by 1/2 the cutter dia. I want to drive the center of the cutter on the geometry and still output G41.

[woody123]

I made my own custom 3D toolpath that is already offest by 1/2 the cutter dia. Now I want to select the custom 3D toopath geometry and still output cutter comp. Wear will offest the geometry again. I want to drive the tool center

on the geometry and still output G41.

Change at point will not allow this for 3D toolpaths.

X-Form offset geometry by 1/2 cutter size and use wear

[shazam/TPP]

then just use in control, that puts the tool center on the geometry. when you backplot it go into your settings and turn off "simulate for cutter comp"

[scooch8292]

If you chose "Control" in the Compesation type box, it will not offset the toolpath with the tool radius and it will post out a G41 if Compensation direction is set to Left or G42 if Compensation direction is set at Right.

 

Or you could just put a negative(tool radius) in the XY Stock to leave box for a 2D Contour.

woody, i believe you are being mislead by the simulation on the screen. as shazam says, turn off comp simulation. In control does drive the cutter on center with comp added to the program. draw a line from x0 y0 to x0 y1., run over it with control comp and post it. you will see it posts correctly.

Yeah!! Eureka and Shazam!!

That's what I want. Yup the simulation was

messin with my melon.

Thank you all for your suggestions and input.

Ain't Mastercam the bees' Knees!!
