28 kwi 2024 · The syntax for a G68 is pretty simple. For Fanuc, use: G68 <alpha> <beta> R<angle> Where, alpha and beta are words for the 2 coordinates of the circle’s center we want to rotate about. For G17, <alpha> is X and <beta> is Y. In the example, we had the circle center at X0Y0. R specifies the angle of rotation in degrees, counterclockwise.

The G68 command (G-code) is used to perform rotation of the coordinate system by a certain angle. X and Y are the coordinates of the point relative to which the coordinate system will be rotated, and R - determines the value of the angle of rotation.
This article presents the basics on producing G-code using nothing but AutoCAD and one of its built-in programming languages. The programming language used is AutoLISP, but the article assumes the reader knows nothing about AutoLISP (this could also be done with VBA or VSTA).
1 INTRODUCTION. G Code is a special programming language that is interpreted by Computer Numerical Control (CNC) machines to create motion and other tasks. It is a language that can be quite complex at times and can vary from machine to machine.
5 wrz 2015 · Instead of programming in terms of absolute coordinates with respect to the selected work piece coordinate system G54 to G59, one can also activate relative or incremental coordinates. In effect, this redefines the current location of the spindle as the origin of a local coordinate system.
