18.1 Grinding-specific tool data

MD18096 $MN_MM_NUM_CC_TDA_PARAM

Loss of data due to reconfiguration

Reconfiguration of the local static NC memory results in a loss of data on the active and

passive file system. We therefore urgently recommend archiving or backing up all relevant

data by creating a series startup file before activating a modified memory configuration.

Access to tool-specific parameters

Tool-specific parameters can be read and written from the part program.

Program code

R10=$TC_TPG5[2]

$TC_TPG6[3]=2000

The following system variable allows the tool-specific parameters for the current tool to be

$P_ATPG[<m>]

<m> = parameter numbewr (data type: REAL)

Parameter 3 ($TPG3[<t>])

Program code

$P_ATPG[3]=R10

Tool length compensations for the geometry axes or radius compensation in the plane are

assigned on the basis of the current machining plane.

The following planes and axis assignments are possible (abscissa, ordinate, applicate for 1st,

2nd and 3rd geometry axis):

; read the current width of tool 2 and store in R10

; write value 2000 to the maximum speed of tool 3.

; read the minimum wheel radius of the current tool and store

(abscissa/ordinate)

Axis perpendicular to plane
