Wire Drawing & Rod Processing worked example

Draw Speed Output at 99% line utilization efficiency: a worked example

Push line utilization efficiency up to 99% and the picture changes. This example computes every intermediate figure at that operating point. Use it when draw speed output in wire drawing and rod processing is being committed and you need a throughput number you can defend.

The inputs for this scenario

  • Wire drawn per shift: 1,200 units (unchanged)
  • Machine running time: 8 hr (unchanged)
  • Line utilization efficiency: 99 % (raised for this scenario; the documented default is 90)

Working through the calculation

  • Applying the documented formula (Raw draw speed output = completed output รท runtime) to the inputs above produces each figure below.
  • At this operating point the engine returns 149 ft / min for effective throughput, the number this scenario is built around.
  • At this operating point the engine returns 150 ft / min for raw throughput.
  • At this operating point the engine returns 99 % for efficiency.
  • At this operating point the engine returns 8 hr for runtime.

How this compares with the baseline

  • Against the tool's baseline example, where line utilization efficiency sits at 90% and the headline result is 135 ft / min, this scenario comes in 10% above the baseline at 149 ft / min.
  • It divides finished output by runtime to get raw draw speed, then multiplies by line utilization efficiency to get the effective speed you can schedule against. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.
