Tool table: Tool data required for automatic tool measurement
For a description of the cycles governing automatic tool
measurement, see the new Touch Probe Cycles Manual,
Chapter 4.
Abbr. Input
CUT. Number of teeth (20 teeth maximum)
LTOL Permissible deviation from tool length L for wear
detection. If the entered value is exceeded, the TNC
locks the tool (status L).
Input range: 0 to 0.9999 mm
RTOL Permissible deviation from tool radius R for wear
detection. If the entered value is exceeded, the TNC
locks the tool (status L).
Input range: 0 to 0.9999 mm
DIRECT. Cutting direction of the tool for measuring the tool
during rotation
TT:R-OFFS Tool length measurement: tool offset between stylus
center and tool center. Preset value: Tool radius R (NO
ENT means R)
TT:L -OFFS Tool radius measurement: tool offset in addition to
MP6530 (see „13.1 General User Parameters") bet-
ween upper surface of stylus and lower surface of tool.
Preset value: 0
LBREAK Permissible deviation from tool length L for break
detection. If the entered value is exceeded, the TNC
locks the tool (status L).
Input range: 0 to 0.9999 mm
RBREAK Permissible deviation from tool radius R for break
detection. If the entered value is exceeded, the TNC
locks the tool (status L).
Input range: 0 to 0.9999 mm
Tool table: Additional tool data for automatic speed/feed rate
calculations.
Abbr. Input
TYPE Tool type (MILL=for milling, DRILL=for drilling or
boring, TAP=for tapping): Press the SELECT TYPE soft
key (3rd soft-key row): The TNC superimposes a
window where you can select the type of tool you want.
TMAT Tool material: Press the SELECT MATERIAL soft key
(3rd soft-key row): The TNC superimposes a window
where you can select the type of material you want.
CDT Cutting data table: Press the SELECT CDT soft key
(3rd soft-key row): The TNC superimposes a window
where you can select a cutting data table.
