Start of program
Absolute coordinates
Dimensions in mm, tool 1
Speed to 1st position
Plunge movement with Z
Feed movement in straight line
Arc about center point
etc...
Rapid speed to zero point
End of program
Bear in mind the following points when writing G code
programs :
The programs must be written using an editor or an external
program
The program name with % sign introduces the real program code,
all preceding lines are remark lines
At least one tool has to be selected and changed, e.g. with T1 M6
in the program head (M6 is absolutely necessary)
Speeds are adjustable with F commands in mm/sec. or mm/min.
defined by paramaters.
The command number can be defined using N commands
For arcs, you can either use the I, J, K commands to define the
center point or R to program a radius. Positive radii produce an
arc less than 180° and negative radii an arc greater than 180°.
Up to 20 subroutines are defined at the end of the main program
after M30, using G98 Lx. The definition ends with G98 L0. The
subroutine call can be positioned anywhere with Lx.
