Example for calling subroutine 53
Subroutine 54 - Turret2_3_ToolDir (tool change direction)
Purpose
Subroutine 54 is used to find out the direction of searching for an adjacent tool and the pre-indexing position (this is, the
previous position of the desired tool in the direction of an adjacent tool). To find out the direction, you need to know the max.
tool number of the turret and the programmed tool number.
You can use this subroutine to control the turret to search for an adjacent tool on a turning machine or a machine centre.
The turret tool position ranges from 2 to 64.
