Function Manual Basic Functions; W1: Tool offset, parameter CUTMOD:

● The CUTMOD NC function is activated when data set 2 is called in the NC program

(CYCLE800 align turning tool). This means that the cutting edge position or the tool

reference point is updated corresponding to the tool orientation:

● When calling a swivel data set for rotational operation in the NC program (CYCLE800 align

tool), the CUTMOD NC function is activated. The cutting edge position, tool angle, cut

direction and tool reference point are thus calculated in accordance with the current tool

orientation following the "Align tool" function.

Manufacturer cycle CUST_800.SPF

During swiveling, all axis positions are approached using the CUST_800.SPF cycle. The call

is exclusively made from the swivel cycle CYCLE800 or from the cycles

E_TCARR (ShopMill) or F_TCARR (ShopTurn).

In cycle CUST_800.SPF, the function markers (_M2: to _M59) are prepared and documented.

Also refer to the following "Structogram CYCLE800".

There are extensions in the CUST_800.SPF cycle for the "Turning on milling machine" function,

see Chapter "Adaptations for CUST_800 (Page 608)".

If you modify the CUST_800, ensure that the G commands of the G groups used are restored

at the end of the CUST_800 (versions S_G_1 to S_G_5!).
