Chapter 3.
Tool-Post Measurement
3.1. Outline
The 2
nd
geometry tool data contained the difference from an internal master tool post to the other tool posts
(slaves). This is the reason why all of the tool posts must be measured with one tool.
The geometry data of this tool must be known and is master tool from now.
The measurement procedure is necessary only one time at the machine start-up. In case of the turret is
changed or of some other mechanical changes all tool posts must be measured again
Furthermore this function is an option, because the MTB is still able to fill up the 2
nd
geometry tool offset
data by hand.
3.2. Preparing of Tool Post Measurement
The measurement of tool post is only provided for axis with the axis support status axis enable.
The master tool has to be mounted to any tool post and with the first measurement the actual Tool Post
number is taken as the master tool post number. After all tool posts are measured and termination of the
procedure the value of the master tool post will be set internal to “0”.
The “OFFSET/GEOMETRY” screen must be selected to get the soft-key “MEASURE” visible and the
master tool geometry offset data has to be fill in at the tool geometry offset data table for example to the first
tool. Basically it’s not important to which tool number the master tool data are filled in, important is that the
master tool with the measured axis is selected by the cursor.
With the rising edge of the signal “TPMP” the tool post measurement is started for the supported axis.
The 2
nd
geometry tool data will be set to the value “999,999” which means unmeasured tool post.
With this situation we have three possibilities:
1. All tool post will be measured and the procedure will be terminated normally.
- All 2
nd
geometry tool data are containing the correct value.
2. Not all tool posts are measured and the procedure is terminated.
- All 2
nd
geometry tool data containing the value “0”.
- An alarm “NOT ALL TOOL POST MEASURED” will be generated and displayed.
3. The power was turning off.
- With the next power on all 2
nd
geometry tool data are set to “0”
- An alarm “NOT ALL TOOL POST MEASURED” will be generated and displayed.
