Formula Used

1) Base Cycle Time
Base Cycle Time = Loading + Processing + Unloading + Inspection

2) Allocated Loss Per Cycle
Allocated Loss Per Cycle = ((Setup + Planned Downtime + Unplanned Downtime) × 60) / Batch Size

3) Performance Adjusted Cycle Time
Performance Adjusted Cycle Time = (Base Cycle Time + Allocated Loss Per Cycle) / Efficiency Factor

4) Good Units Per Cycle
Good Units Per Cycle = Units Per Cycle × (1 − Reject Rate)

5) Effective Time Per Good Unit
Effective Time Per Good Unit = Performance Adjusted Cycle Time / Good Units Per Cycle

6) Cycles and Output Rates
Cycles Per Hour = 3600 / Performance Adjusted Cycle Time
Good Units Per Hour = Cycles Per Hour × Good Units Per Cycle
Good Units Per Shift = Good Units Per Hour × Shift Hours

7) Takt Comparison
Takt Time = (Shift Hours × 3600) / Required Units Per Shift
Compare takt time against effective time per good unit to judge demand fit.

Detailed Output Notes

Base cycle time captures the direct task time within one cycle. It does not include batch-level losses.

Allocated loss per cycle spreads setup and downtime across every unit cycle, which makes planning more realistic.

Performance adjusted cycle time inflates cycle time when the line runs below ideal efficiency.

Effective time per good unit shows how long one saleable unit truly takes after performance and quality losses.

Takt comparison checks whether available production pace can support the required daily demand.

FAQs

1) What is machine cycle time?

Machine cycle time is the time needed to complete one production cycle. It may include loading, processing, unloading, and inspection steps for each run.

2) Why does downtime matter in cycle analysis?

Downtime reduces real output even when ideal machine speed looks strong. Allocating downtime across a batch gives a more realistic time per cycle.

3) Why include reject rate?

Rejects lower the number of good units produced from each cycle. Including reject rate converts machine pace into usable output pace.

4) What does efficiency change in the result?

Efficiency adjusts the cycle for speed loss, minor stops, and other performance gaps. Lower efficiency increases the practical time needed for each cycle.

5) What is effective time per good unit?

It is the adjusted production time required for one acceptable unit. This is often more useful than raw machine time for capacity planning.

6) What is takt time in this tool?

Takt time is the maximum available time per unit if the shift must meet a target demand. It helps compare capacity against required pace.

7) Can I use this for multi-cavity or multi-part cycles?

Yes. Enter total good pieces made in one cycle as units per cycle. The calculator will then convert cycle speed into unit-level output.

8) When should I export the report?

Export after you confirm the assumptions. CSV works well for spreadsheet review, while PDF is useful for sharing production estimates with teams.
