Surgical Robotics Manufacturing worked example

Arm Assembly Labor at 12% setup, torque-check, and inspection allowance: a worked example

This scenario runs the arm assembly labor calculation on the strong side: 12% setup, torque-check, and inspection allowance, with every other input held at its documented default. Use it when arm assembly labor in surgical robotics manufacturing is being added to next week's schedule and you need an honest hours estimate.

The inputs for this scenario

  • Robot arms to assemble: 120 arms (unchanged)
  • Arm assembly throughput per minute: 12 arms / min (unchanged)
  • Setup, torque-check, and inspection allowance: 12 % (raised for this scenario; the documented default is 10)

Working through the calculation

  • Applying the documented formula (Base arm assembly labor time = arm assembly labor workload รท arm assembly labor completion rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 11.2 hr for required arm assembly labor time, the number this scenario is built around.
  • At this operating point the engine returns 10 hr for base arm assembly labor time.
  • At this operating point the engine returns 12 % for arm assembly labor allowance applied.
  • At this operating point the engine returns 12 pieces / min for arm assembly labor completion rate.

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 1.82% above the baseline at 11.2 hr.
  • Use it when planning a build wave, balancing assembly stations, or estimating the labor content of a surgical arm during quoting. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Required arm assembly labor time: 11.2 hr (headline result)
  • Base arm assembly labor time: 10 hr
  • Arm assembly labor allowance applied: 12 %
  • Arm assembly labor completion rate: 12 pieces / min

Run it with your numbers

  • Every input above is editable in the live Arm Assembly Labor calculator, which recalculates instantly and can be shared with the inputs intact.
