R specifies the angle of rotation in degrees, counterclockwise.įor Mach3, we use a slightly different syntax: In the example, we had the circle center at X0Y0. Rather than having the coordinate words vary with which plane is selected (G17, G18, or G19), Mach3 just uses the “A” and “B” words. The first G68 in the example would be written like so:Īs you can see from the example, multiple G68’s just replace the R or center values. There is the option on some controls to make G68’s relative, rather than absolute. In this case, rather than having multiple G68’s replace the values, they are relative to the values. For most controls, the decision of whether subsequent G68’s are relative or absolute is a parameter. For Mach3, it is a function of whether the “I” word is present (think “I” for “Incremental”). The value (address) of the word is ignored, but any I will cause Mach3 to treat the coordinate as relative. Here are some examples (for completeness, we include the subprogram example too): Other Uses for G68 Coordinate Rotationīeside the obvious usefulness of rotating the coordinates before calling a subprogram so that the same cut may be applied along a circular path, there are other important uses for G68. – Simplify your part program by creation of subprograms that repeat cutting operations multiple times along an arc. This will also reduce the memory requirements of the part program. – Align work that is not exactly aligned to the coordinate system. For example, suppose you wanted to run without tramming in a fixture. If you can probe the fixture to determine its angle, you can apply a G68 to “zero out” that angle and then run the part program.

This can reduce setup time by reducing the need to be accurate and trammed in. – If a part program is written for a bigger machine and has more Y-travel (extents) than X, you may be able to rotate the coordinates so the long axis is aligned with yo ur X and still be able to run it. – You may be able to nest more parts on your machine table if you can perform arbitrary rotations on them.

Write a program similar to the example that takes some cutting operation, puts it in a subprogram, and then uses G68 to rotate it to multiple positions around the circle.CIMdata PLM Industry Summary Online Archive – A part that is otherwise too large for a machine might fit if you could take advantage of the extra long diagonal dimension.
