ProE cutter compansation

[javed08]

Hi I am new to ProE, I want to creat simple 2D programme with cutter companation ( G41, G42) so that my operator can use any available cutter to machine 2D profile. What is the procedure to do that?

Hej Javed,

The procedure to apply cutter compensation to a Pro/E toolpath is to apply the NC Sequence parameter "CUTCOM" to "ON". You will find it in the advanced section of parameters in the NC Seq.

Note a few things however:

1. Not all Sequences have this option to set. This depends on the type. Obviously drilling sequences dont have them, but neither does for example "surface mill". This is since this sequence isnt supposed to be used in such a manner. It does have 3DCOMP though, but that requires some effort in the PP.

2. A Volume sequence only applies the cutcom statement on the profiling parts of its path. This means that if a volume sequence is doing both ROUGH and PROF it will NOT compensate the ROUGH part. If your stock allow is big enough of if the used tool doesnt differ that much from the programmed tool, you should be ok anyways.

3. You will most likely be needing to set a lead in/out aswell as maybe a Normal movement for the controller to be able to read in the G41/42.

4. Normally Pro/E will output CLdata on the center of the mill. This varies from how you usually manually program so pls be aware that the tooltable in the machine must be set accordingly. I.e not the Tool radius(Diamter) but rather how much smaller it is than the programmed tool (wear). In Heidenhain you can take care of this by DR in the tool call line. DR is the programmed value of the tool, and the controller compensates with the value in the tool register.
(8 TOOL CALL 27 Z S8000 DL+Q5 DR-20.000 For example)

You can also set the output to be on the side of the mill from the Workcell Window. On the bottom of that window you have a flyout that will allow you to make this setting.

Good luck, J
