PREPARATORY FUNCTIONS
PREPARATORY FUNCTIONS, also known as ‘G’ codes, set various machining modes within the control. There are two basic types of preparatory functions, MODAL and ONE-SHOT.
 

MODAL PREPARATORY FUNCTIONS

Modal Preparatory Functions establish a machine mode which stays in effect until canceled by another Preparatory Function belonging to the same group. Once a Modal ‘G’ code is programmed, it need not be repeated in successive program blocks.
 

VALID PREPARATORY FUNCTIONS (G CODES)

G00 Rapid Traverse Mode (Default)
G01 Linear Interpolation Mode
G02 Clockwise Circular and Helical Interpolation Mode
G03 Counter Clockwise Circular and Helical Interpolation Mode
G04 Dwell (One-Shot; Affects Fixed Cycles)
G09 Precision Cornering (One-Shot)
G17 XY Plane Selection
G19 XZ Plane Selection
G40 Cutter Compensation OFF(Default)
G41 Cutter Compensation Left
G42 Cutter Compensation Right
G61 Precision Cornering Mode ON
G64 Precision Cornering Mode OFF(Default)
G70 English Units of Measure*
G71 Metric Units of Measure*
G80 Fixed Cycle Cancel(Default)
G81 Drill Cycle
G82 Drill with Dwell Cycle
G83 Deep Hole Drilling Cycle
G84 Tapping Cycle
G85 Boring Cycle
G90 Absolute Machining Mode(Default)
G91 Incremental Machining Mode
 
MISCELLANEOUS FUNCTIONS
Miscellaneous Functions, or ‘M’ codes, cause machine-related action(i.e. coolant control, tool changes, etc.). Each Miscellaneous Function is explained below.
 

VALID MISCELLANEOUS FUNCTIONS (M CODES)

M00 Program Stop
M01 Planned Stop
M02 End of Program
M03 Start Spindle Clockwise
M04 Start Spindle Counterclockwise
M05 Spindle OFF (Default)
M06 Change Tool
M07 Mist Coolant ON
M08 Flood Coolant ON
M09 Coolant OFF
M25 Z-Retract
 
 
NC FORMAT DESCRIPTION
DEFAULT VALUES

Upon power up or reset of the control, the system presets the internal mode registers to default Modal Preparatory and Miscellaneous Functions. Default Modal Preparatory Functions are:

G00 Rapid Traverse Mode
G17 XY Plane Selection
G40 Cutter Compensation OFF
G64 Precision Cornering OFF
G75 Multi-Quadrant Circular Interpolation Mode
G80 Fixed Cycle Cancel
G90 Absolute Machining Mode
Default Miscellaneous Functions are:
M05 Spindle OFF
M09 Coolant OFF

Communicating with HURCO Milling machines.
RS232 connections on AMTS BX-MPU Brd.:
9-Pin to 9-Pin 9-Pin to 25-Pin
2 ------ 3 2 ------ 2
3 ------ 2 3 ------ 3
5 ------ 5 5 ------ 7
 
 
NOTE: For cables over 25 ft., connect shield to one end of the cable, either on Pin 5 of the 9-Pin or Pin 1 of the 25-Pin.
Connect cable to Com2 on right and make sure you have selected a proper baud rate on the board.(The longer the cable, the slower the baud rate selection should be.) Make sure the computer is set for the same baud rate as well as 7 data bits, 2 stop bits, even parity and xon/xoff protocol.
To download G-code to Hurco you must have the buffer empty. To do this you must press ‘CHECK’ then "ENTER" then ‘1’ (program edit) then press "MASTER CLEAR".
Once the buffer is empty press ‘3’(load program) then ‘3’ (remote) then "NEXT BLOCK". The sceen should read ‘Reading Leader’.
You can now send your program to the Hurco machine. When the buffer fills it will automatically DNC. Keep the computer link running and start the machine running, as it uses up the program lines it will ask the computer to send more. This will continue until it reaches an end of program command.
NOTE: The buffer is approximately 20,000 characters.
