Detailed Description

MD22550 $MC_TOOL_CHANGE_MODE = 0

MD22550 $MC_TOOL_CHANGE_MODE = 1

The following problems can occur if tool management is not active:

• D compensation data set missing

• Error in part program

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.

Error in part program

The options for intervention in the event of an error depend on how the tool change was

programmed (defined via machine data:

MD 22550 $MC_TOOL_CHANGE_MODE).

; Tool preparation + 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)

; Tool preparation

; 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)
