Tool direction in robot CAD CAM


I wanna define a tool in robotic CAD CAM area but according to attachment, tool direction is -X, while the robot coordinate different. give me a recomend to match the CAD CAM coordinate (attach file 1) with robot coordinate(attach file 2).



Re: Tool direction in robot CAD CAM

Hi Meysam,


The pocket orientation with +X pointing upwards is a strict requirement of the CAM system before we introduced the robots. this is the way how machine tools are modeled for many years and if we break this - simulation and other features would not wor.

the good news is that for Robots we do not have to change that. we can stay with the same definition, but when posting - address the correct frame direction. every post processor has the following seting that will take care of it:Spindle Direction.jpg

 Please try it and let us know if this resolves the problem

That wasnt useful

I fixed it by use s head between tool and spindle.

Thank you

Re: Tool direction in robot CAD CAM



I have the same problem, that I couldn't find a solution to fix the connection between pocket and tool to the same configuration as my real robot.


Did you find a solution?


Best regards,

Hi Lars,


Not sure what the issue you are facing is, but I can add another piece of information which I hope would not confuse you more:

Also note that the definition of the pocket frame is a full coordinate system, while the post setting only refer to the tool axis direction. The rotation of the frame is done around the Y axis. So in your initial pocket definition make sure that the coordinate system you set has the +X pointing upwards (which you probably already do) and also the +Y direction aligns with the setting of the physical robot.

if this does not help please add more details of the issue you face.

Hi Eddy,


yeah, that was the issue I was talking about and changing the tool vector in the post configuration was the right solution Smiley Wink


But I have another problem with the robotic rules. I will send you a private message because this isn't belonging to this subject here
