Measuring cycle for measuring a tool during rotation
The TNC determines the longest tooth of a rotating tool by positioning
the tool to be measured at an offset to the center of the touch probe
system and then moving it toward the measuring surface until it
contacts the surface. The offset is programmed in the tool table under
Tool offset: Radius (R-OFFS).
Measuring cycle for measuring a tool during standstill (e.g. for
drills)
The TNC positions the tool to be measured over the center of the
measuring surface. It then moves the non-rotating tool toward the
measuring surface of the TT until it touches the surface. To activate
this function, enter zero for the Tool offset: Radius (R-OFFS) in the tool
table.
Measuring cycle for measuring individual teeth
The TNC pre-positions the tool to be measured to a position at the side
of the touch probe head. The distance from the tip of the tool to the
upper edge of the touch probe head is defined in offsetToolAxis. You
can enter an additional offset with Tool offset: Length (L-OFFS) in the
tool table. The TNC probes the tool radially during rotation to
determine the starting angle for measuring the individual teeth. It then
measures the length of each tooth by changing the corresponding
angle of spindle orientation. To activate this function, program TCH
PROBE 31 = 1 for CUTTER MEASUREMENT.
You can run an individual tooth measurement of tools with
up to 20 teeth.
