Common (Mill & Lathe) G-Codes
††††††††††††††††††††††† Feed Move Group
*G00 † Rapid linear move. [X,Y,Z] Moves the machine at the fastest rate possible to the X,Y,Z location specified
*G01 † Linear feed move [X,Y,Z,F] Moves the machine a the specified feed rate (F) to the X,Y,Z location specified
*G02 † Circular feed move; CW [X,Y,Z,F,R (or I,J,K)] Moves the machine, in a clockwise circular path to the X,Y,Z, location specified with radius R, or with a center point defined relative to the start point in the X,Y,& Z axis by I, J,& K respectively.
*G03†† Circular feed move; CCW [X,Y,Z,F,R (or I,J,K)] Same as G02, but opposite direction of movement.
† G04†† Dwell† (P) Causes the machine to pause for a period determined by parameter P.† If P<value> has a decimal point, the dwell is †x.x seconds; otherwise dwell is in milliseconds.
† G28†† Return to machine home.† Causes the machine to return to itís X0,Y0,Z0 position at a rapid rate.
††††††††††††††††††††††† Coordinate System Group
*G53 † Machine coordinate system (MCS). Cancels G-54 thru G59
*G54-G59 Work coordinate offsets. †Allows the user to establish one or more alternative coordinate systems to correspond to individual work coordinate systems (WCS)
††††††††††††††††††††††† Units Group
*G70†† Inch Programming (This facility uses inch programming unless otherwise stated)
*G71†† Metric Programming
††††††††††††††††††††††† Common Canned Cycles (See Canned Cycles Page)
† G80 † Cancel all canned cycles
† G81†† Basic drill cycle
† G83†† Peck drilling cycle
† G84†† R.H. tapping cycle
† G85†† Basic boring cycle
† G86†† Boring cycle, spindle stop at bottom, rapid out
††††††††††††††††††††††† Absolute / Incremental Mode
*G90†† Absolute Programming Mode† All X,Y,Z coordinates determined from a single from a single origin.
*G91†† Incremental Programming Mode† Next X,Y,Z, coordinates are determined from current location
††††††††††††††††††††††† Feedrate Mode Selection
*G94†† Feedrate input in inches (or millimeters) per minute.† Primarily used on mills
*G95†† Feedrate input in inches (or millimeters) per revolution.†† Primarily used on lathes
Common (Mill & Lathe) M-Codes
† M00†† Machine stop †stops the machine, requiring the operator to restart the program to continue.
† M01†† Optional stop †stops the machine as above only when the optional stop button has been pressed prior to this command in the program
† M02†† Program end† tells the machine control that the program is complete
† M03†† Spindle start clockwise (S) at the RPM specified by the S word accompanying the code
† M04†† Spindle start counter clockwise as above
† M05†† Spindle stop
† M06†† Tool change (T) commands to machine to exchange the tool currently in use for the one called by the T word
† M07 / M08 Coolant on† If the machine is equipped with only one coolant system, it is generally commanded by the M08
† M09†† Coolant off
† M19†† Spindle orientation
† M30†† Program stop and rewind to program start
Lathe Only G-codes
† G33†† Thread cutting, constant lead †[ †††††]
† G34†† Thread cutting, increasing lead ††[ †††††]
† G35†† Thread cutting, decreasing lead †[ ††††]
† G50†† Maximum Spindle RPM for constant surface speed operation
††††††††††††††††††††††† Lathe specific canned cycles (See Canned Cycles Page)
† G73†† OD or ID roughing cycle [ †††††]
† G74†† Rough facing cycle [†††††† ]
