5.3.4 Changing the settings for the blank

In the operating area "Program" press the HSK 1.6

Press the VSK 1.1 "Blank".

The setting window for the blank opens.

Optionally change the graphic view on the blank by

pressing the VSK 2 "Graphic view".

Enter the parameters for the blank in the corre-

sponding input fields (see parameter list in section

Confirm your inputs by pressing the VSK 8 "Accept"

or abort with pressing the VSK 7 "Cancel".

A new program block "WORKPIECE" is inserted into

the Work plan (alike the picture below).

5.4 Subprogram

If you require the same machining steps in the programming of different

workpieces, you can define these machining steps in a separate routine.

You can then call this subroutine in any program.

Identical machining steps therefore only have to be programmed once.

ShopTurn does not differentiate between main program and subprogram.

This means that you can call a "standard" sequential control or G code

program as subprogram in another sequential control program.

In this subprogram, you can also call another subprogram.

The maximum nesting depth is 8 subroutines.

If you want to call a sequential control program as a subroutine, the

program must already have been calculated once (load or simulate

program in "AUTO" mode). This is not necessary for G code

subroutines.
