2.6.1 Tool change
Depending on the type of tool changer, the following options are possible:
• Machine with automatic tool changer.
• Machine with manual tool changer.
In either case, the CNC acts as follows:
• The CNC executes the subroutine associated with the tool change (general machine parameter
P60 "TOOLSUB").
• The CNC sends to the PLC all the necessary information for it to manage the tool change.
• The CNC assumes the new tool values (offsets, geometry, etc).
Example of how to manage a manual tool changer.
• Subroutine 55 is defined as the subroutine associated with the tools.
General machine parameter P60 "TOOLSUB" = 55.
The subroutine associated with the tools may contain the following information:
• The tool is selected after executing the subroutine.
General machine parameter P71 "TAFTERS" = YES.
• The movement to the change point only takes place when executing an operation or cycle of
the TC mode.
• Once the subroutine is completed, the CNC executes function T??, sends to the PLC all the
necessary information for it to manage the tool change and assumes the new tool values (offsets,
geometry, etc.).
(SUB 55)
(P100 = NBTOOL)
; Assigns the requested tool number to P100.
(P101 = MS3)
; If spindle counterclockwise P102=1.
G0 G53... XP?? ZP??
; Movement to the tool change point.
M5
; Spindle stop.
(MSG "SELECT T?P100 AND PRESS START")
; Message to select the tool change.
M0
; Stop the program stop and wait for START to be pressed.
(MSG "" "")
; Deletes previous message.
(IF P102 EQ 1 GOTO N10)
; Restores the spindle turning direction.
(IF P101 EQ 0 RET)
M3
(RET)
N10 M4
(RET)
When a cycle has been selected (CYCEXE other than 0)
The program is being executed (OPMODA bit 0 = 1).
