How do you calculate automated inspection capacity?

Multiply parts per cycle by available cycles for gross capacity, then multiply by uptime and pass rate. With 1 part per cycle, 2,400 cycles, 95% uptime, and 97.5% pass rate, you get 2,223 good parts per shift.

What is the difference between gross and good capacity?

Gross capacity is the theoretical maximum — here 2,400 parts. Good capacity subtracts the 120 parts lost to downtime and the 57 removed by rejection, leaving 2,223 parts that actually pass.

Why does inspection pass rate reduce capacity?

Rejected parts still consume a cycle but do not move downstream as good output. At a 97.5% pass rate, 57 parts per shift are removed, so they count against deliverable good-part capacity.

What uptime should an automated inspection system have?

Mature vision cells commonly run 92% to 98% uptime. The 95% default costs 120 parts a shift here; pushing it toward 98% would recover most of that loss.

How do I know if my inspection cell is a bottleneck?

Compare the 2,223 good parts per shift against the parts your production line delivers per shift. If the line outpaces inspection, the cell throttles output and you need faster cycles or a second station.

Can parts per cycle be more than one?

Yes — multi-part fixtures or wide field-of-view cameras inspect several parts per cycle. Raising parts per cycle scales gross capacity directly and is often the cheapest way to add throughput.

Machine Vision & Industrial Inspection AI calculator

Automated Inspection Capacity Calculator

Automated Inspection Capacity estimates how many good parts an automated vision or gauging system can actually clear in a shift, after accounting for downtime and the parts removed by rejection. Production planners and vision integrators use it to confirm an inspection cell can keep pace with the line feeding it and to size throughput before committing to a station. It is the difference between a theoretical spec-sheet rate and the real number of good parts that move downstream. Getting it right prevents inspection from becoming a hidden bottleneck that starves the rest of the line.

What this calculator does

Calculate the total number of parts an automated vision inspection system can inspect in a shift, based on parts per machine cycle, available shift cycles, system uptime, and inspection pass rate.
Use it when sizing an automated inspection system for a new line or checking whether an existing system can handle an increased production volume without becoming a bottleneck.
It computes good parts inspected per shift from gross capacity reduced by system uptime and the inspection pass rate.

Formula used

Gross inspection capacity = parts per cycle x available cycles per shift
Good parts inspected = gross capacity x system uptime x pass rate

Inputs explained

Parts inspected per machine cycle:
Available inspection cycles per shift:
Automated system uptime:
Inspection pass rate:

How to use the result

Use it when sizing an automated inspection cell or checking whether its throughput matches upstream production rate.
It treats uptime and pass rate as steady averages, so it will overstate output during ramp-up, changeovers, or quality excursions when rejects spike.
