OPERATION
The rules above govern the use of all codes for programming the Haas (and other) controls. The concept of
grouping codes and rules that apply will have to be remembered if we are to effectively program the machine
tool. The following is a discussion of the codes most basic to the operation of the machine.
G CODES:
G00 Rapid traverse motion; Used for positioning and during non-cutting moves.
G01 Linear interpolation motion; Used for actual machining and metal removal. Governed by
programmed feed rate.
G02 Circular interpolation - Clockwise
G03 Circular interpolation - Counterclockwise
G28 Machine home (Rapid traverse)
G40 Cutter compensation cancel
G41 Cutter compensation to left of path
G42 Cutter compensation to right of path
G43 Read tool length compensation
G54 Work coordinate #1 (Part zero)
G80 Canned cycle cancel
G81 Drill canned cycle
G82 Spot drill canned cycle
G83 Peck drill canned cycle
G84 Tapping canned cycle
G90 Absolute programming
G91 Incremental programming
G98 Initial point return
G99 Reference plane return
M CODES:
M00 Program stop. Press CYCLE START button to continue.
M01 Optional program stop. Press optional stop key on control panel on M01 code.
M02 End of program. Cannot continue.
M03 Start spindle forward (Clockwise). Must be accompanied by a spindle speed.
M04 Start spindle reverse (Counterclockwise). Must have a spindle speed.
M05 Spindle stop
M06 Tool change command. Must have a tool number in the same line. This command will
automatically stop the spindle.
M08 Coolant ON command
M09 Coolant OFF command
M30 Program end and rewind to beginning of program
M97 Local subroutine call
M98 Subprogram call
M99 Subprogram return, or loop
Note: Only one îš“Mîš” code can be used per line. The îš“Mîš” code will be the last item of
code to be performed, regardless of where it is located in the line.
