BASICS
Tool Data Measuring
Aim of the tool data measuring:
The CNC should use the tool tip for positioning, not
the tool mount reference point.
Every tool which is used for machining has to be
measured. The distances in both axis directions
between tool mount reference point and tool tip are to
be measured.
In the so-called tool register the measured length
corrections, the cutter radius and the cutter position
can be stored.
Every tool offset number D1 - D99 is related to a tool.
The correction number can be any register number,
but has to be considered with tool call in program.
Example
The length corrections of a tool in the tool turret
station 4 have been stored as correction number 41.
Tool call in program: T4 D41
The address T marks the position in the tool turret,
the address D marks the correction number belonging
to the tool.
The length corrections can be measured half-
automatically, cutter radius and cutter position have
to be inserted manually.
The cutter position must always be inserted!
Inserting the cutter radius is only necessary for using
the cutter radius compensation with this tool.
The tool data measuring occurs for type 1-9:
L1 : in -X direction absolute from point "N"
in radius
L2: in -Z direction absolute from point "N"
R: cutter radius
Type: cutter position (1-9)
The tool data measuring occurs for type 10:
L1: in -Z direction absolute from point "N"
Type: drilling tool (10)
Direction of the length correction for the tool types
