2.10.5 Starting execution at a specific point in the program

2-120
If you only want to execute a particular section of a program on the
machine, there is not obligation to start execution of the program from
the beginning, you can also start processing from a specific program
block or text string.
The point in the program at which you wish to start machining is called
the "target".
ShopMill distinguishes between three different target types:
•
ShopMill cycle
•
Other ShopMill block or G code block
•
Any text
For the "Other ShopMill block or G code block" target type, you can
again define the target in three different ways:
•
Position cursor on target block
This is ideal for straightforward programs.
•
Choose point of interruption
Machining resumes at the point at which it was interrupted earlier.
This is especially convenient in large programs with multiple
program levels.
•
Specify target directly
This option is only possible if you know the precise data (program
level, program name etc.) of the target.
Once the target has been specified, ShopMill calculates the exact
starting point for program execution.
With "ShopMill cycle" and "Any text" target types, the calculation is
always based on the end of the block. When calculating the starting
point of all other ShopMill blocks and G code blocks, you can choose
between four options.
1. Calculation to end point:
During a block search, ShopMill makes the same calculations as
when executing a program. The program is executed from the end
of the target block or from the next programmed position of the
target block.
2. Without calculation
ShopMill performs no calculations during block search, i.e. the
calculation is skipped up to the target block. The parameters within
the control contain the values valid before the block search.
This option is only available for programs that exclusively comprise
G code blocks.
