Post-Cut Finishing Time Cheat Sheet
Estimate finishing, deburring, cleaning, inspection, and packaging labor from your own shop route. Use timed samples and production records instead of public default time ranges.
Why Finishing Time Matters
Laser cutting quotes can miss real labor when the estimate stops at machine time. Finishing work may include deburring, oxide removal, surface preparation, inspection, packaging, and documentation.
The defensible input is a shop-measured route: the method used, the operator or machine involved, the inspection requirement, and the loaded labor rate applied to that work.
Deburring Methods Comparison
Choose the finishing route from the actual edge condition, part geometry, customer requirement, and equipment available in your shop. Then time a representative part or batch.
| Method | Best Fit | Quote Input to Capture |
|---|---|---|
| Manual deburring | Selective work, prototypes, internal features, and jobs that need operator judgment. | Timed sample by material, edge condition, and operator skill level. |
| Belt or disc grinding | Flat edges, accessible profiles, and repeat work with consistent edge requirements. | Routing record with tool type, abrasive condition, and pass count. |
| Brush deburring machine | Flat sheet parts that can pass through the machine without damage or masking problems. | Machine cycle record, load/unload labor, brush condition, and inspection result. |
| Tumbling or vibratory finishing | Batchable parts that tolerate media contact and shared processing. | Batch cycle, media, load size, unload labor, and part-protection notes. |
Finishing Time by Cut Quality
Cut quality should drive the finishing route. Capture what the part actually needs, then use the measured result in the quote.
Clean Edge
Confirm whether the part only needs light edge break, wipe-down, and inspection. Save the timed route if the finish requirement is repeatable.
Burr or Dross Present
Record the tool used, number of passes, operator effort, and rework rate. Heavy cleanup should be quoted as a separate labor step, not hidden inside machine time.
Cosmetic or Coating Requirement
Add the required cleaning, masking, surface prep, coating handoff, and packaging steps to the route before calculating final cost.
Additional Finishing Operations
| Operation | Quote Input |
|---|---|
| Cleaning and residue removal | Timed wipe-down, solvent, ultrasonic, or blast-cleaning step from the routing sheet. |
| Surface treatment preparation | Masking, hanging, passivation, oiling, edge sealing, or coating-prep labor from the shop route. |
| Inspection and quality control | Visual inspection, dimensional checks, first-article review, sample plan, or customer-required report. |
| Packaging and documentation | Wrapping, bagging, labeling, certificates, packing lists, and shipping protection policy. |
Quote Workflow
- 1. Define finish requirement. Record edge break, burr removal, cosmetic surface, coating prep, inspection, and packaging expectations.
- 2. Time a representative route. Use a sample part or recent production job with the same material, edge condition, tools, and quality standard.
- 3. Apply loaded labor rate. Connect the measured time to the labor rate defined in the hourly cost structure guide.
- 4. Push into quote tools. Use the finishing calculator and final laser quote so post-cut labor is visible before margin is applied.
Cost Impact Formula
Keep the formula simple and auditable. The values should come from your route, time study, and labor policy.
Finishing cost = measured finishing time x loaded finishing labor rate
Quote cost = laser cutting cost + material cost + finishing cost + packaging + overhead + margin
Control rule: If cut quality, tool choice, operator route, inspection level, or packaging changes, do not reuse the old finishing time without review.
Make Post-Cut Labor Visible
Connect measured finishing time to hourly rate, laser cutting cost, and final quote margin before the job is sent to the customer.
