Case study · Dimetix
Quick responseIn a metal cutting and machining machine, a Dimetix laser sensor replaces the machine's guide rail, which previously allowed human error in some batches. In some customers, the sensor sends the length to the PLC, which enables cutting or machining only when the correct length is reached. Accuracy ± 1 mm and repeatability ± 0.3 mm.
Case statement
Cutting and machining devices are common and widespread tools in the metal processing industry.
| Fact | Worth |
|---|---|
| Industry | Cutting and machining industries |
| Application type | Measurement of dimensions and length |
| Customer need | Perform cuts and holes with precision and repeatability |
| Aim | Avoid quality problems with your customers and optimize production operations |
Previous situation and improvement
- Previously: the operator had to be guided by the machine's rule.
- Problem: Human error was present in some manufacturing batches.
- Improvement: the Dimetix sensor measures length.
- Automation (some customers): the sensor sends the information to the PLC, and the PLC determines when the correct length is available to enable the operator to perform the cutting or machining.
