The available evidence documents one focused method for finding the midpoint of a probe-measured distance on a Mitsubishi M70 control: enter the measurement as an inline division expression. The evidence does not identify the offset screen, probing cycle, axis, or final work-offset write command, so confirm those machine-specific details before changing an active offset.
Scope and Known Limits
The source names “M700/70 M,” while the described calculation method is explicitly attributed only to M70 controls. Treat applicability to the M700 as unconfirmed. The method calculates half of a measured distance; it does not by itself establish whether that result must be added to or subtracted from the current machine position.
| Item | Evidence-supported detail |
|---|---|
| Confirmed control | M70 |
| Purpose | Divide a probe-measured distance by two to locate its midpoint |
| Entry form | Prefix the measurement with = and append /2
|
| M700 applicability | Not confirmed by the supplied evidence |
Calculate the Measured Midpoint
Enter the measured distance as an expression instead of calculating it separately. The documented entry is:
=105.105/2Mathematically, this evaluates to 52.5525. Use the actual probe measurement in place of 105.105. Preserve the measurement unit used by the control; dividing by two does not change the unit.
Apply the Method
- Probe the required distance and record the displayed measurement.
- In the applicable numeric-entry field, enter
=, the measured value, and/2. - Confirm that the control evaluates the expression to half of the measured distance.
- Before writing a work offset, determine the required sign and reference direction from the machine position, probing setup, and selected axis. These details are not defined in the evidence.
Verify Before Machining
Independently divide the recorded probe measurement by two and compare it with the control's evaluated result. Then verify the resulting zero with a non-cutting position check appropriate to the machine. Do not infer the sign, axis, offset register, or coordinate relationship from the division expression alone.
FAQ
How do I divide a probe measurement by two on a Mitsubishi M70?
Enter the measurement as =measurement/2 in the applicable numeric-entry field. The documented example is =105.105/2, which calculates 52.5525.
Does the M70 midpoint expression automatically set the work zero?
The evidence confirms only the midpoint calculation. It does not identify the offset register, axis, sign, or command required to write the calculated value as the work zero.
Can I use the same midpoint entry on a Mitsubishi M700?
The source title mentions M700 and M70, but the described expression method is explicitly reported only for the M70. Verify expression evaluation on the M700 before applying any offset change.
