In-machine measurement is a system that measures the dimensions of a machined part inside the machine, without removing it.
Dimensional deviations are compensated automatically on the basis of the measured data, keeping quality stable while machining continues.
A Closer Look
During long, continuous runs, dimensions gradually drift because of tool wear and thermal displacement of the machine.
Because nobody can check dimensions during unattended operation, there is a risk of producing defective parts without anyone noticing.
In-machine measurement prevents this.
By measuring dimensions periodically and applying compensation automatically when a deviation is detected, dimensions are held stable from the first part of the lot to the last.
Instead of "noticing after defects appear," it enables preventive quality control that "compensates before defects occur," making unattended operation something you can run with confidence.
