Thermal Spray, Hardfacing & Wear Coatings worked example

Robot Path Time at 7.2% indexing + reposition allowance: a worked example

Suppose indexing + reposition allowance falls to 7.2%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Robot Path Time estimates how long the spray robot spends actually traversing the programmed path to lay down a thermal spray or hardfacing coating.

The inputs for this scenario

  • Total spray path length to traverse: 120 units (held at the documented default)
  • Robot traverse / deposition rate: 12 units / hr (held at the documented default)
  • Indexing + reposition allowance: 7.2 % (the input this scenario stresses; the baseline uses 10)

Working through the calculation

  • The calculation starts from the formula this tool documents: Base robot path time time = required work รท processing rate.
  • Adjusted run time works out to 10.72 hr at these inputs, and this is the headline figure for the scenario.
  • Base run time works out to 10 hr at these inputs.
  • Allowance applied works out to 7.2 % at these inputs.
  • Process rate works out to 12 pieces / min at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where indexing + reposition allowance sits at 10% and the headline result is 11 hr, this scenario comes in 2.55% below the baseline at 10.72 hr.
  • It divides total path length by the robot's traverse rate for base spray time, then adds an allowance for indexing and repositioning between passes. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.

Results at a glance

  • Adjusted run time: 10.72 hr (headline result)
  • Base run time: 10 hr
  • Allowance applied: 7.2 %
  • Process rate: 12 pieces / min
