How do you calculate vision station throughput?

Multiply parts per cycle by available cycles per shift for gross capacity, then multiply by uptime and first-pass yield. Here 1 x 2,160 = 2,160 gross, x 0.94 x 0.97 = 1,969.49 good parts per shift.

What is the difference between gross capacity and good throughput?

Gross capacity (2,160 here) is what the station could inspect if it never stopped and never rejected. Good throughput (1,969.49) is what survives downtime and rejects, the number that actually moves to the next operation.

What is a good first-pass yield at a vision station?

For mature processes, 97% and up is healthy, as in this example. Yields below the low 90s usually mean a process problem upstream or an over-tight inspection threshold flagging good parts.

Is downtime or yield costing me more parts?

Compare the loss lines. Here downtime costs 129.6 parts and rejects cost 60.91 parts, so uptime is the bigger lever. Fixing the more expensive loss first gives the fastest throughput gain.

How do I increase good parts throughput?

Raise uptime by stabilizing the cell, improve first-pass yield by tuning thresholds or fixing the upstream process, or add cycles. Lifting uptime from 94% to 98% on this station recovers roughly 84 parts a shift.

Does throughput include reworked parts that later pass?

No. The figure counts parts that pass on the first attempt. Parts that fail, get reworked, and re-inspected are not added back, so true sellable output may be slightly higher after rework.

Machine Vision & Industrial Inspection AI calculator

Vision Station Throughput Calculator

Vision Station Throughput tells you how many good parts a machine vision cell actually clears in a shift after you discount downtime and rejects. Line engineers and capacity planners use it because a station's rated cycle count is a fantasy number; real output is throttled by uptime and first-pass yield. Knowing the true good-parts figure lets you match the vision station to upstream production, set realistic OEE targets, and spot whether downtime or rejects is the bigger drain. It turns a nameplate spec into a number you can actually plan a shift around.

What this calculator does

Calculate the number of good parts that a vision inspection station can produce in a shift, based on inspection rate, available shift cycles, system uptime, and first-pass yield at the station.
Use it when loading a production schedule and you need to know whether the vision inspection station can clear the required volume in the available shift time.
It computes good parts inspected per shift by scaling gross inspection capacity down by system uptime and first-pass yield.

Formula used

Gross inspection capacity = parts per cycle x available cycles per shift
Good parts throughput = gross capacity x system uptime x first-pass yield

Inputs explained

Parts inspected per cycle:
Available inspection cycles per shift:
Vision system uptime:
First-pass yield at inspection station:

How to use the result

Use it when sizing a vision cell against line demand, setting shift output targets, or diagnosing whether downtime or rejects is limiting throughput.
It applies uptime and yield as flat shift-average multipliers, so it won't capture clustered downtime, a yield that drifts during a run, or rework that recovers some rejected parts.
