| − | The side laser scans the bar as it moves into the final loading location, which gives the software a “heads-up” for the length of the bar. If the length is different to expected, the software will then use the sensor array to measure the bar length.
| |
| − | | |
| − | | |
| − | There are 2 measurement methods because the side laser is not 100% reliable, especially on shorter lengths below 3000mm. However, it does mean the system does not have to grip and measure / reoptimize each bar length, so improves the cycle time.

| − | The sequence is as follows
| |
| − | | |
| − | | |
| − | 1. During the conveyor loading, measure the length using the side laser
| |
| − | | |
| − | 2. Once loaded to backfence, check the backfence sensor array.
| |
| − | | |
| − | 3. If the sensor array rough measurement does not match the laser –
| |
| − | | |
| − | a. If the laser measured length < infeedLaserRemeasure, continue and measure with rear sensors
| |
| − | | |
| − | b. If the laser measured length < infeedLaserRemeasure, flag an error that laser has not measured correctly.
| |
| − | | |
| − | c. If it does match, use the laser value to reoptimize the bar if it is different than expected
| |
| − | | |
| − | 4. Load and Grip bar, if necessary, measure accurately with rear sensor array</translate>
