FMS Insight Engineering Pages

The Engineering page is intended for the part programming engineers. We suggest they bookmark this page and visit it directly. The page can be used after a new part-program is introduced to closely watch the timings of the new program. The page can also be used to stay on top of problematic programs which are frequently interrupted.

Screenshot of Machine outliers

First, there is a table which shows cycles from the last three days which are statistical outliers. The outlier detection is based on the median absolute deviation of the median, which is more resilient to outliers than the standard deviation. There are two reasons that a machine cycle will appear here:

  • If the actual time on the machine is far away from the median actual time, the cycle will be displayed. Cycles of this type indicate that the program was interrupted and took longer than expected.
  • If the expected machine time from the job is far away from the median actual time, the cycle will be displayed. Cycles of this type indicate that the expected time is unrealistic (as long as enough cycles are available to obtain good statistics). In this case, the expected machine time in the flexibility plan should be adjusted to be equal to the median time. Alternatively, perhaps the program should be changed to improve the machine time.

Next, the planned and actual machine hours for the past 7 days are shown. The data can be toggled between a bar chart and a table. Anything older than 7 days is available as part of the monthly review on the flexibility analysis page.

Finally, the page contains a chart of all machine cycles from the past 3 days. The chart can be zoomed by clicking and dragging, filtered to specific parts and/or pallets, and toggled to a table. Clicking on any point allows more details about the cycle to be loaded. Anything older than 3 days is available as part of the monthly review on the flexibility analysis page.
