2.1.6
Compensation block in case of error during tool change
MD22550
If a tool preparation has been programmed in the part program and the NCK detects an error
(e.g., the data set for the programmed T number does not exist in the NCK), the user can
assess the error situation and perform appropriate tasks, in order to subsequently resume
machining.
The tool change may be programmed independently, depending on the machine data:
MD22550 $MC_TOOL_CHANGE_MODE (new tool compensation with M function).
MD22550 $MC_TOOL_CHANGE_MODE = 0
T= "T no."
; Tool prepa tool change in one NC block,
; i.e., when T is programmed a new D compensation becomes
; active in the NCK (see
; machine data MD20270 $MC_CUTTING_EDGE_DEFAULT)
MD22550 $MC_TOOL_CHANGE_MODE = 1
T= "T no."
; Tool preparation
M06
;Change tool
; (the number of the tool-change M code can be changed),
; i.e., when M06 is programmed a new D compensation becomes
; active in the NCK (see
; machine data MD20270 $MC_CUTTING_EDGE_DEFAULT)
The following problems can occur if tool management is not active:
•
D compensation data set missing
•
Error in part program
Note
The "tool not in magazine" problem cannot be detected since the NCK did not have
access to any magazine information during tool compensation.
D compensation data set missing
Program execution is interrupted at the block containing the invalid D value (regardless of
the value of machine data MD22550). The operator must either correct the program or
reload the missing data set.
To do this, he needs the D number for the flat D number function, or otherwise the T number
as well. These parameters are transferred when the alarm is triggered.
