Industrial automation companies in Malaysia are no exception when it comes to meeting international quality criterion for finished products. To accomplish this, Coordinate-Measuring Machines (CMM) are used for a variety of applications including reverse engineering, quick prototyping, testing, profiling and evaluation.
CMMs are used to measure geometrical dimensions of objects and can be operated manually or computer. These machines are made up of a i) probe (which could be mechanical, optical, laser, etc.) on a ii) moving arm, and the iii) machine table. Data collected from CMMs are fed into a 3-D modelling software (such as CAD) where it is used for further work in conjunction with turnkey automation systems.
Precision machining companies in Malaysia use CMMs for their ability of taking different measurements such as dimensional, profiling, angles, depth mapping, imaging and shaft measurements.
How Industrial automation companies in Malaysia categorize CMMs.
- Measuring length – The maximum distance that a probe is able to move between the x, y and z axis.
- Capacity – The maximum size of the object that the CMM can take in.
- Resolution – The smallest increment that can be measured. Smaller increments mean higher accuracy.
- Speed – The speed at which a CMM is able to move and take measurements.
- Weight capacity – the maximum weight that the CMM table can accommodate.
When CNC or DCC control mechanisms are used.
Computer numerical control, or CNC, are best suited when high volumes of work needs to be done, such as a production environment, or when highly precise or complex movements are required. CNC-controlled CMMs are more expensive.
Manually operated CMMs, on the other hand, requires a human operator to work it and take measurements down. Manual CMMs are best used in prototyping and design purposes where constant adjustments are required but high-throughput isn’t necessary.
Types of Probes
- Touch point – inexpensive and widely used.
- Laser triangulation – Mainly used as scanning probes. Provides a continuous flow of data.
- Line lasers – Used to quickly measure non-linear surfaces and contours. Useful in reverse engineering.
- Camera – Used to photograph and measure points.
- Video Camera – Inspecting workpieces through video imaging and thus are useful for flat parts.
