Surgical Robotics Manufacturing worked example

Arm Assembly Labor at 7.2% setup, torque-check, and inspection allowance: a worked example

Suppose setup, torque-check, and inspection 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. Estimate arm assembly labor for surgical robotics manufacturing using production-ready inputs so teams can plan labor hours, schedule the work, or check whether the job fits the available shift time.

The inputs for this scenario

  • Robot arms to assemble: 120 arms (held at the documented default)
  • Arm assembly throughput per minute: 12 arms / min (held at the documented default)
  • Setup, torque-check, and inspection 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 arm assembly labor time = arm assembly labor workload รท arm assembly labor completion rate.
  • Required arm assembly labor time works out to 10.72 hr at these inputs, and this is the headline figure for the scenario.
  • Base arm assembly labor time works out to 10 hr at these inputs.
  • Arm assembly labor allowance applied works out to 7.2 % at these inputs.
  • Arm assembly labor completion rate works out to 12 pieces / min at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where setup, torque-check, and inspection 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 converts a count of robot arms and a per-minute assembly throughput into base and allowance-adjusted assembly labor hours for a surgical robotics build. 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

  • Required arm assembly labor time: 10.72 hr (headline result)
  • Base arm assembly labor time: 10 hr
  • Arm assembly labor allowance applied: 7.2 %
  • Arm assembly labor completion rate: 12 pieces / min

Run it with your numbers
