4.1.2 Automatic block search
It may be used to restore the program history up to the block where the execution was interrupted.
The CNC remembers in which block the execution was interrupted, thus not being necessary to set
the stop block.
If the program is interrupted inside an internal cycle, it will behave as follows:
If it is a pocket cycle (G66, G67, G68, G87, G88) or a multiple cycle (G60, G61, G62, G63, G64),
when doing a home search, it restores the history up to the last subblock inside the completed
cycle.
In the rest of the canned cycles (G69, G81, G82, G84, G85, G86), it is interrupted inside the
cycle, it restores the history up to the cycle calling block.
To access the automatic block search, press <BLOCK SELECTION> and press one of the operating
modes <EXEC G SEARCH> or <EXEC GMST SEARCH>.
Then, press the <STOP BLOCK> and <AUTOMATIC SEARCH> softkeys.
The <AUTOMATIC SEARCH> softkey is only shown when the block that has been stored for the
automatic search is located among those of the program and once pressed places the cursor in that
block.
Once the block has been selected, the screen shows the text STOP=HD:PxxxLxxx that indicates
the location of the program, the program number and the program line. After pressing [CYCLE
START] the CNC searches the block and once simulated up to the stop block, it removes the previous
text.
Then, the CNC determines the axes that are out of position and shows them so they can be selected.
If it has also searched for G functions and the program contains M, S, T functions that must be
executed, the menu shows the softkey <PENDING MST EXEC> so those functions are executed
after pressing the softkey and validating it with [CYCLE START].
Tool inspection:
Pressing the <TOOL INSPECTION> accesses tool inspection.
• Pressing the <DIS PENDING MST> softkey displays the M, S and T functions that have been
simulated and are pending to be executed.
• Pressing the <MDI> softkey access that mode and lets the user execute the desired blocks.
Quick block search
The quick block search is oriented to CAD/CAM programs that contain at the beginning the blocks
that set the machining conditions and then a number of motion blocks. In this type of programs, the
interruption point may be found much faster.
However, if there is a block in the middle of the program that changes the machining conditions set
at the beginning of the program, finding the interruption point may be slower.
With new block search, some of the motion blocks already executed will NOT be simulated. The CNC
does not simulate the blocks between the last point that do not contain coordinates, labels or
comments and the block of the interruption point of the program.
This way, it skips between blocks stopping at the block just before the interruption block; in other
words, at the block executed last. This lets resume the program from a slightly previous position to
the interruption point, thus ensuring proper continuity of the machining operation that was being
carried out.
When interrupting, the CNC automatically identifies whether it is possible to perform a quick block
search or not in the interrupted program. If it is possible, this search may be initiated with the
"Automatic Search" softkey.
If in the execution prior to the interruption there are blocks associated with canned cycles and/or
calls to blocks that involve a level change, like for example PCALL or RPT, the quick search will not
be applied, only the normal search.
