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.
