5 axis tool linear compensation
The 5 axis tool linear compensation corrects the programmed block end points
depending on the type of milling head used in short linear blocks with G01. If a
tool breaks, the milling machine can carry on from the point of the breakage if
a tool with the programmed radius but a different length is chucked. The
difference in length is entered as the tool length compensation in tool offset
type 40.
This is only possible if the programs have been written taking the tool length
and cutter radius into consideration.
The 5 axis tool length compensation is called up with NC MD 5010 and tool
type 40. The tool length (different in length as compared with the old tool) is
stored in tool parameter P2. In the case of milling machines with a nutating
head, the permanent nutating angle must also be entered in MD 20.
