Robotic arm perpendicular to surface

LinuxCNC can control up to 9 axes of coordinated motion.

Hello,
I study industrial engineering and I'm going to do a hot wire cutting machine mounted on a 6-axis robotic arm as my final project.
I need a software that allows me to do the cnc program while keeping the robot perpendicular to the surface.

If you are asking whether LinuxCNC can perform coordinated moves of a robot arm to achieve straight-line moves in cartesian space then the answer is "yes"

Not the best example of a linuxCNC controlled robot arm, but this video is running conventional XYZ G-code (the LinuxCNC splash screen)

My question is if the robot can be programed to keep the axis of a mill perpendicular to the surface that is milling

And the answer is "Yes".

For an Industrial Engineering project I think you will find that LinuxCNC is the right choice, because if there is anything in the software that doesn't do what you want, you can change it.

I suggest you download the LiveCD from this web site, boot a PC from it (any PC, you don't need to install anything, you can run from the CD) and then start LinuxCNC from the menu, then choose the Sample-Configs -> Puma -> Puma config
Then re-arrange the windows so that you can see both the Axis GUI and the simulated machine.
You can rotate the simulated robot picture with Shift-drag (keyboard and mouse together) and move it about with click-drag.
Then press the home-all button.
Move both jog-speed sliders to higher numbers.
You can now select each axis and jog it with the +/- buttons. (In "Joint Mode" at this point)

Now select View -> World Mode
The axes change to XYZ

Now you can jog the tool-tip in XYZ space.

I think you will like what you see
