G01 is used for a Linear interpolation motion; Used for actual machining and metal removal. It is governed by a programmed feedrate in inches (or mm) per minute.
G02 Circular Interpolation, ClockWise
G28 Machine Home (Rapid traverse)
G40 Cutter Compensation CANCEL
G54 Work Coordinate #1 (Part zero offset location)
G80 Canned Cycle Cancel
G03 Circular Interpolation, CounterClockWise
G81 Drill Canned Cycle
G42 Cutter Compensation RIGHT of the programmed path
G90 Absolute Programming Positioning
G91 Incremental Programming Positioning
G03 Circular Interpolation, Counterclockwise
G98 Canned Cycle Initial Point Return
G41 Cutter Compensation LEFT of the programmed path
G99 Canned Cycle Rapid (R) Plane Return
G43 Tool LENGTH Compensation +
G83 calls the Peck Drill Canned Cycle
G00 is Rapid traverse motion; Used for non-cutting moves of the machine in positioning quick to a location to be machined, or rapid away after program cuts have been performed.
M03 Starts the spindle CLOCKWISE. Must have a spindle speed defined.
M05 STOPS the spindle.
Use an M06 Tool change command along with a tool number will execute a tool change for that tool.
Use an M30 to end Program and Reset to the beginning of program.
Complete the program for the part shown, use Cutter Compensation: 12 Points

The M00 code is used for a Program Stop command on the machine.
It stops the spindle, turns off coolant and stops look-a-head processing.
Pressing CYCLE START again will continue the program on the next block of the program.
The M01 code is used for an Optional Program Stop command.
Pressing the OPT STOP key on the control panel signals the machine to perform a stop command when the control reads an M01 command.
It will then perform like an M00.
Use M08 to turn Coolant ON.
Use M09 to turn Coolant OFF.
