All types: Block search as of a specific program position (file offset)

Set a jump point with block search

The NC program can be started with a file offset in combination with any block search type. The file offset defines a jump to a known position in the NC program.

The program part before the jump point is ignored. Evaluation starts at the jump point as for a program shortened by file offset.

The jump point can be specified in addition to the continuation position of the block search. The jump point must be placed before the continuation position.

The full technology scope must be reproduced at the jump point so that machining can continue. The NC program then runs as usual up to a continuation position in the commanded block search type.

This method saves time in the block search with large NC programs.

During block search, the NC program is processed up to the specified continuation position (green section) without axis motion after the jump point (grey section). The axes are then moved for real (white section).

Definition of jump point

The jump point is defined in a similar way to the continuation position of block search before the start of an NC program by

      mc_command_file_offset_w

(see section Program start at file offset).

File offset to define a jump point can also be used without block search. Processing then starts directly at the jump point as for a program shortened by file offset.
