CMM, an acronym for Coordinate Measuring Machine, is the Turkish word for “Coordinate Measuring Machine”. A CMM is a device used to measure the physical geometric properties of an object. Dimensional inspection is used in process control; its results determine parameters. In order to achieve the desired output the production process is typically carried out with a coordinate measuring machine with computer-controlled dimensional inspection. Sometimes the CMM probe, a very precise mechanical system designed to move a measurement, to determine the coordinates of points on a workpiece surface. A CMM consists of:
- A work area where parts are fixed, a sensor to detect object surfaces, and a mechanical assembly to move an object sensor around the work area,
- Computer measurements with software used to calculate part sizes according to the sensor.
How does CMM work?
CMMs are also known as coordinate measuring machines, are used to check the dimensions of parts produced, performed with conventional instruments such as micrometres and height gauges metrology, aerodynamics and usually are used to check the presentation of the automated manual QC checks. There are several types of CMM, but they all essentially use ruby or similar-tipped probe tips or laser or similar non-contact probes, which move around the piece, taking the coordinates of the surfaces and features as they move. These are then compared to the CAD file in which the part was designed. CMMs can be manual or fully automatic.
The dimensional capabilities of CMM generally include position, roundness, steepness, parallelism, flatness, angularity, surface profile, profile of a line, symmetry, concentricity, linearity, and data quantification.
Which sectors need CMM measurement?
Measuring the physical geometric properties of an object allows comparison with approved product properties. Assessments include initial part assessment and critical dimensional profile measurements. Determining whether products meet specification requirements prior to production and / or shipment can reduce costly reworking and subsequent delays.
As mentioned, CMM measurement can be performed on-site or in-house. Accuracy is an important factor in CMM measurement, so many customers prefer to partner with a third party rather than using equipment that may be in place at the factory. The machines themselves change when it comes to accuracy, but equally important is the experience and skill of the operator.
KALKANCI CMM measurement
CMM measurement, which are used in almost every aspect of industrial production and which are of great importance in the final checks of the resulting products, have an important place in the quality control process. Proven to be one of the most practical and well-known types of quality control, the CMM is also of great importance for providing high-precision control. In order to offer the best possible results to our valued customers, the KALKANCI brand uses CMM measurement in its quality control processes.
Our laboratories have three different CMM measurement machines from the leading ZEISS, Mahr and Mora brands. These devices, which measure projects and mass production parts meticulously and quickly, can measure the physical geometric characteristics of products with a high level of success. In addition, they have been chosen by KALKANCI for their well-designed software, user-friendly interfaces and decisive outcomes.
