Dimensional control

Quality control in production is necessary to monitor the manufacturing process in order to make the necessary corrections and thus ensure that the manufactured parts meet the requirements. In the specific field of microtechnology, tolerances can be very tight, requiring special attention to measurement. Historically, these were carried out using contact measuring benches; these are now often replaced by optical devices.

Automated optical inspection ensures the quality of manufactured parts while optimizing manufacturing costs. This inspection can be carried out by sampling with a testing device such as the qmtprojector-100 or 100% with a testing station integrated into an automatic process.

Full-field optical measurement
Full-field optical devices enable fast, accurate, and non-contact inspection of all part characteristics. Dimensions can be measured with sub-micron accuracy in less than a second.
High-level business functions allow for the measurement of complex features such as gears or threads without programming. Since the measurement is non-contact, there is no risk of damage to the part and the operator has no influence on the measurement.

The importance of installation for turned parts
To accurately measure a turned part, it is necessary to position it so that its axis is perfectly perpendicular to the optical axis. This operation is generally carried out by placing the part on two blades and offsetting the height of one of the blades; this operation is time-consuming and generates a risk of measurement error.
To facilitate this operation, the qmtvline fixture was developed. It consists of two flat transparent supports that create a certain angle between them, allowing the part to naturally "lean" thanks to gravity. The optical path of the light emitted by the source is modified so that the image seen by the camera is no longer from above but from the side, thus the measured dimensions correspond to reality. It is therefore no longer necessary to precisely position the part along its axis of rotation, so no more planing operations.

Dynamic measurement for beat measurement
Full-field optical devices enable fast, accurate, and non-contact inspection of all part characteristics. Dimensions can be measured with sub-micron accuracy in less than a second.
Some characteristics such as runouts and splits require dynamic measurement with part rotation. They can be measured on the same equipment with the specific wheeltest fixture and the qmtwheeltest-vision software function.
