Utilization Report Information Layout
When you first access the Utilization Report, the Utilization Report for All Machines displays. The Utilization Report for All Machines provides the following information and capabilities:
- All Utilization Components: A line chart that shows utilization percentage over time for all machines in the environment and for all utilization components. The line chart can be changed to show all utilization components for selected shifts and to compare shifts by individual utilization components.
- Shifts: A table that lists utilization percentage by shift for the selected time range
- Machine Groups Summary: A table that lists utilization percentage by machine group for the selected time range, with the capability to view a detailed utilization report for each machine group.
- Machines Summary: A table that lists utilization percentage by machine for the selected time range, with the capability to view a detailed utilization report for each machine.
The following sections present the information and capabilities provided by each of these utilization analysis tools.
Utilization Chart: All Utilization Components
The following sections explain the information and functionality offered by the Timelines Dashboard highlighted in the figure above.
Selecting a Machine Group
By default, the Timelines Dashboard shows the cycle timelines for all machines in the environment. You can click on the associated pull-down menu to select an existing machine group, and click the Apply button to see only the machine timelines for that group.
Setting the Timeline Date Range
By default, the Timelines Dashboard shows the machine cycle timelines for the current date. You can change the date range displayed by clicking on the date fields and selecting your desired date range as well as the from/to times on each date. Click the Apply button to apply the new date and time range to the timelines.
Machine Timelines Table
As highlighted in the illustration in Timelines Dashboard Information Layout, the Machine Timelines table provides the following information and functionality:
- Machine name and percentage that the machine has been Active (in-cycle) for the displayed time period
- Interactive machine cycle status timelines for each machine displayed in the current timeline view
- "Arrow" buttons to scroll the timeline view forward to the next day or back to the previous day, and a Today button that returns the timeline view to the current day view.
- Date and time scale for the timeline
Machine Cycle Status Timelines
The Timelines table contains interactive, graphical bars that are the machine cycle status timelines for each machine in the environment. Clicking on a timeline bar opens the detailed timeline dashboard for that machine.
Timeline Bar Color Code
The machine cycle status timeline bar indicates machine cycle status over time using the following color code:
The definitions of each status seen in the machine cycle timeline are as follows:
- Active: Machine is in-cycle (up) and processing parts at this time.
- Inactive: Machine is out-of-cycle (down) and not processing parts at this time.
- Disconnected: Machine is not communicating with MachineMetrics at this time.
- Setup: Machine is in Setup stage in MachineMetrics at this time.
Increasing the Time Scale Granularity of the Timeline
By default, the timeline shows machine cycle status in one hour increments. You can expand the timeline to increase the time scale granularity all the way to show time in one-second increments. This can be done in the main Timelines table but is most useful when viewing the detailed timeline for an individual machine. Expanding the timeline for an individual machine to one minute or less will show when each part was produced and the text associated with faults or other machine adapter messages associated with other downtime conditions.
To increase the time scale granularity of a machine cycle timeline, do the following:
- Hover over any area of the timeline.
- Spread out the timeline to the desired granularity. This will be done in different ways depending on the system you are using to view the timeline:
- PC Mouse: Roll the scroll wheel up to expand the timeline, and back to compress it.
- Touch Pad/Screen or Mac Mouse: Use the two-finger spread method to expand the timeline, and the pinch method to compress it.
- To view a section of time that is off-screen after the timeline is expanded, click and drag the timeline left or right to the desired time.
The following figure shows an example of a detailed individual machine cycle timeline expanded to 15-second time scale granularity:
Categorizing Machine Downtime
Being able to categorize machine downtime is one of the most important and valuable features of MachineMetrics. Categorizing machine downtime in MachineMetrics helps companies understand the main reasons why their machines go down, which is the critical first step in being able to analyze and minimize the costly disruptions to manufacturing processes caused by unplanned downtime. In most cases, machine downtime should be categorized at the time it occurs by the machine operator using the tablet interface.
This section explains how Manager and Executive users can use the Timelines Dashboard to categorize machine downtime that was not initially categorized (or was incorrectly categorized) by the operator.
The following provides an example procedure for how you can categorize machine downtime using the Timelines Dashboard:
- Hover over a section of a machine cycle timeline bar in the Machine Timelines table when the machine was at Inactive status.
- MachineMetrics will display any message that was provided from the machine adapter for that time period. The message may indicate whether the machine was just idle, was down because of a machine fault, or was inactive in some other state. The text will vary by machine adapter and by the integration with MachineMetrics.
Below is an example of the hover text for downtime because of a machine fault in a CNC machine named CNC 104:
- Click on the timeline bar for the machine to open the detailed timeline view of that machine.
- If you do not already know the reason for the downtime, you may be able to identify the downtime based on the fault or condition that is associated with the downtime for the same location in the machine cycle status timeline. Below is an example of machine fault hover text for the downtime identified in the previous example for machine CNC 104.
- Click on the Inactive section of the timeline bar that contains the downtime you want to categorize to open the Categorize Downtime dialog. You can also access this dialog by clicking the time entry that corresponds to the same time period in the Downtime table.
- Click the Reason pull-down menu and select the category you want to assign to the downtime.
You can also do the following in this dialog:
- Select the Planned checkbox to indicate that the downtime was planned
- Add a message to further explain the reason for the downtime
- Uncategorize downtime that is already categorized
- Split the downtime period into different categories
- Merge two downtime periods into the same downtime category
- When you have completed your entries, click the Save Changes button.
- The time period will now appear as categorized downtime in the Downtime table and in MachineMetrics reporting.
Using the Downtime Table
A Downtime table is provided in the detailed timeline view for individual machines that provides the following information on each downtime event that occurred in the selected time period:
- Start: Time the downtime started
- Duration: Length of the downtime
- Reason: Category assigned to the downtime
- Message: Explanatory message that was entered with the reason.
- Planned: Whether the downtime was planned, unplanned, or a downtime event that was planned but exceeded the planned downtime limit.
Viewing Long Downtime Events
MachineMetrics categorizes downtime as either Long or Micro in reporting based on the Microstop Duration value entered in the Downtime section of the System Settings page. The Duration field heading in the Downtime table contains a pull-down menu that can be used to filter the Downtime table to only show downtime events that meet the MachineMetrics criteria for Long downtime.
Searching and Filtering by Downtime Reason
The Reason field heading in the Downtime table contains a text search field. Text entered in this field will automatically search and filter the Downtime table to only show downtime events that contain the entered text in the downtime category name.
Viewing Downtime by Planned/Unplanned Event Type
The Planned field heading in the Downtime table contains a pull-down menu that can be used to filter the Downtime table to only show downtime events that were planned, unplanned, or planned but exceeded the planned downtime limit.
