Bend Radius Check with installed or routed bend radius of 15 in: a worked example

Push installed or routed bend radius up to 15 in and the picture changes. This example computes every intermediate figure at that operating point. Use it when routing a hose assembly in a machine or system and need to confirm the tightest bend meets the manufacturer minimum bend radius requirement.

The inputs for this scenario

  • Installed or routed bend radius: 15 in (raised for this scenario; the documented default is 6)
  • Minimum bend radius (manufacturer spec): 4.5 in (unchanged)
  • Reference bend radius: 4.5 in (unchanged)

Working through the calculation

  • Applying the documented formula (Bend radius margin = installed bend radius - minimum bend radius) to the inputs above produces each figure below.
  • At this operating point the engine returns 10.5 in for absolute margin, the number this scenario is built around.
  • At this operating point the engine returns 233 in for bend radius margin (in).
  • At this operating point the engine returns 15 value for available amount.
  • At this operating point the engine returns 4.5 value for required amount.

How this compares with the baseline

  • Against the tool's baseline example, where installed or routed bend radius sits at 6 in and the headline result is 1.5 in, this scenario comes in 600% above the baseline at 10.5 in.
  • Computes the absolute bend radius margin (installed minus minimum) and that margin as a percentage of a reference radius. 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.

Results at a glance

  • Absolute margin: 10.5 in (headline result)
  • Bend radius margin (in): 233 in
  • Available amount: 15 value
  • Required amount: 4.5 value
