A: #68=1： Probe of Fix Position Tool Sensor
This mode uses 2 probe sequences to first establish the height of the tool sensor and then
probers the tool onto the sensor. In so doing it updates the value held in #69 ["Thickness of tool
sensor"].
It uses the following parameters:
#69 ["Thickness of tool sensor"] It updates this parameter with the measured tool height.
Note that this parameter can have a negative value:
It measures the "height" of the tool probe comparing the stock z-zero (defined during the
zeroing sequence) and z coordinate during the tool contact with the sensor. So depending on the
work setup (tool probe surface is higher or lower then the stock/code z-zero) - it could be both
positive and negative, as it's not a real probe height - it's a difference between part/stock zero and
surface of the probe.
#71 ["Initial tool's position"]
0 = "current position" Where the probe is in the current reference frame. All examples relate to
G54
1 = "fixed position" The position of the tool sensor in the MACH machine Coordinate
If “fixed” it uses:
These 3 locate the tool sensor in the Machine co-ordinate system (MACH)
#72 ["Initial probe position on X axis"]
#73 [“Initial probe position on Y axis"]
#74 ["Initial probe position on Z axis"]
#75 [“back distance after probe"] How far to retract in Z after the contact
Operations:
Step1: The user has to manually zero the z axis onto the tool table;
Step2: To meansure the thickness of the sensor(#69 ["Thickness of tool sensor"]):
If #71=0,then move the Z axis manually onto the sensor,then press twice,the system
start to probe.
If #71=1,and #72,#73,#74 already set a value,press the key twice,the system will move
the Z axis to the positon of Mach coordinate and probe.
Then the #69 ["Thickness of tool sensor"] can have a number in system.
Step3: Change a new cutter or in the situation you need to find Z positon again,do the probe
action again,then you can find the Z position.
Please note when you build a new coordiante(for example zero all axis),the #69 value will
become 0,you will have to probe twice.
