Newbie: Tool Diameter in Mach problems.
« on: July 13, 2009, 07:58:32 AM »
I am probably doing something wrong but I have set up tool 1 in Mach3 Mill to have a diameter of 3mm in the tool table but it still cuts as though it has a diamter of zero mm.
Any suggestions?

Yes - Assuming you have set up the tool table correctly, you must then select the tool,( a T command) so that the correct number of tool shows on the screen (or you can just alter the DRO on the screen if you wish), but then you must tell your program to take the diameter into account - see G40, G41 or G42.

You might have difficulty in selecting the right G41 or G42. There was a very good post by Graham Waterworth which described this - if you search his posts.

 Also, just because you select the Tool and say G41, this doesn't mean the tool will move to the correct cutting position immediately. It needs a move prior to the one where you cut, to get the tool onto the right offset.
Not me driving the engine - I'm better looking.
