The Usage view shows in a stacked bar chart which machine states were in the selected period in percentage distribution. Again, only the occupancy time (machine switched on) is evaluated.
View Usage
Main use | green | The machine is producing. |
|---|---|---|
Main use exceedance | dark green | The machine is producing, but it loses power due to large gaps between the workpieces. The optimal frequency is therefore "exceeded". This use only exists for continuous machines. |
Ancillary use | light blue | The machine is set up, adjusts automatically or feeds parts. Especially with batch size 1 machines, ancillary use is part of the normal production process. |
Ancillary use exceeding | blue | For some machines, target times can be set for manual intermediate times (e.g. loading parts onto CNC machines). If these are exceeded, then the status of secondary use is exceeded. |
Waiting position | yellow | The machine is switched on and ready to produce, but is not being used. Reasons for this can be that there is no operator at the machine or that the material is missing. But it may also be that the machine was forgotten to switch off (control voltage off). |
Disruption | red | The machine had a malfunction. Malfunctions are not exclusively technical malfunctions of the machine. Other events (e.g. opening the machine hood or other safety equipment) are also considered malfunctions. |
Maintenance | violet | The machine was serviced. |
Ideally, the main usage is 100%. However, since every machine has set-up times as well as process-related waiting times, experience has shown that these are 100% not achieved.
Tooltip
By clicking on a data point/bar, you will see a tooltip showing the time and value at that time.
