Different parameters may be set against each device on the factory floor that will allow chrome to determine how to process bar on that machine and what types of bar can be processed on any given machine.
To access the configuration function from Cut Optimiser, right click a device in the production lines grid and select "Maintain Device"
Device Details
This tab details basic information regarding the device:
- Device Description - Description of the device
- Device Type - Operation type of the device e.g. Shearline, bender, off-coil etc
- Factory Centre - Which Factory Centre unit the device is installed at
- Device Parent - The device is connected to an upstream device e.g. a Bender will normally be downstream from a shearline
- Site - Which site location the device is installed at
- Cut File Folder - Some machines can receive cut files electronically. Where are the files to be written to?
- Scrap Rate - The scrap rate assumed for the device and expressed as a multiplyer e.g. 1.04= 4% scrap
- Attached Scanners - The scanners attached to this device (May be more than one)
- Show In Optimiser - Display the device in the Optimiser application
- Cut Using Optimisation - Cuts will be performed using stock bar and optimised for yield
- Off-Coil machine - Is the device a combination shear/bending type device
- Default Offcuts to Bay The bay number from the Loading Bay tab to be used for dumping offcust
- At Position - Allows Offcuts to be stored at either end of the assigned bay e.g. 0= AT start moving forward, 12000 at end moving backwards.
Once all details have been entered as required press the save button to update the changes. If a parts are present in the Parts to cut grid they will be cleared as parameters to the device affecting them may have been updated.
Device Capacities
Against each device different processing metrics can be stored which determine how a device will process tags for the specified bar.
This includes information in addition to how many bars the device will process simultaneously, feed and loading rates along with arbitrary timing values to determine how long work will take to pass through the machine.
If the device does not include an entry for a particular bar type (In the above case N12 bar) you will not be able to move production work to this device for N12 type work.
| Value Name | Description |
| Product | Bar Diameter Designation (N10, N12 and so on) |
| Cycle | The amount of bars that can be cut or bent at once |
| Bin Capacity | Max Feed length |
| Feed Rate | Feed Rate of the machine in Millimeters per second |
| Bending Time | Timen take to bend an angle less than 90 degrees |
| Bending Time 90 | Time taken to bend an angle more than 90 degrees |
| Fatigue (%) | The % that the feed rate will decline with each bend |
| Cycle Interval | Time taken from Cut or Bend to starting of next Cut or Bend Cycle |
| Tag Interval | Time taken to tag product |
| Bundle Interval | Time Taken to bundle product |
| Load Time | Loading time per tonne of steel |
| Cut Sheet Weight | Optimal weight for cut sheet on that machine, used for smart splitting |
Typical Error messages when performing Optimisation
When performing optimisations on shearlines the following error messages may indicate the following problems with the device configuration:
- No Bays Configured or cleared for use:
This error indicates either:
- No output bays have been configured for the device:
Define the output rack dimensions for the Shearline and which Bender (if applicable) are fed from the defined rack:
- No output bays are marked as cleared (i.e. the bays are able to be used and bot blocked for some reason like maintenance etc):
Mark the bays as clear to allow the optimiser to use the bays:
- No output bays have been configured for the device:
- No Offcut bays configured or cleared for use:
Bays may have been defined for the shearline but one has not been nominated as the default bay for offcuts:
Enter the bay number and required offset for offcuts to be used for offcuts generated during the cut cycles:
