MANUFACTURING ROBOT — PROJECT BRIEF AND CALCULATION WORKSHEET
Yenra | 2026-09-07 | https://yenra.com/manufacturing-robots/

Use: prepare a brief for an integrator. Label each input Measured / Quoted /
Assumed and record its date and evidence. This is planning, not cell approval.

Owner / date / project revision:
Process start event and end event:
Problem to solve and current baseline:
Required good parts per shift:
Part drawings, variants, mass, surfaces and arrival condition:
Quality criteria and measuring method:
Fixture / gripper / feeder requirements:
Machine interfaces and data requirements:
Changeovers, replenishment, rejects and fault-recovery responsibilities:
Site utilities, space and environmental requirements:
Qualified safety/integration lead and applicable requirements:

CAPACITY (one sequential cycle per part)
A. Planned production time after scheduled exclusions, minutes/shift:
B. Demonstrated complete cycle, seconds/part:
C. Availability within A, fraction from 0 to 1:
D. Good-output fraction, from 0 to 1:
Estimated good parts/shift = A * 60 / B * C * D
Define the exclusions in A:
Define losses in C and D; avoid double-counting:
For overlapping machines or parallel tasks, use a separate timing model.

Fictional example: A=420, B=30, C=0.85, D=0.98 => 699.72, about 700.
Demand 800 => about 100 short. At B=25 => 839.664, about 840.
A proposed faster cycle must be demonstrated.

COST SCREEN — use one currency and annual periods
Currency:
E. Installed capital (equipment, tooling, integration, site work, training):
F. Annual gross cash benefit:
G. Additional annual operating cost:
Net annual benefit = F - G
Simple payback in years = E / (F - G), only when net benefit is positive.
If net benefit is zero or negative, state that a positive simple payback
cannot be calculated. Separate released staff capacity from cash savings.
Record exclusions: tax, financing, discounting, ramp-up, residual value, etc.

Fictional USD example: E=120000, F=70000, G=22000.
Net=48000 per year; simple payback=2.5 years.
Lower-benefit case: F=52500 => net=30500; payback=3.9344 years (~3.93).
These values are invented, not quotations, forecasts or verified savings.
