For this turned 303 part, the second-op route is cheaper by $117.80 at one and $10.10 at 10, while live tooling is cheaper by $0.67 at 100 ($17.47 live tooling versus $18.14 second op). Live tooling carries more setup but a shorter repeat cycle; a prototype or an available VMC can still favor the second operation.

The 303 stainless example part
The reference part is a two-inch pin with an end hole and a cross feature represented by the turning example part. The exact cross-hole angle, flat width and datum scheme still need a drawing review. The comparison is about routing economics, not a promise that every Swiss lathe can reach every feature.
How the quantity break works
A live-tool program has a longer setup and specialized tooling, then a short repeat cycle. Turning and milling separately has two workholding plans, transfer inspection and another chance to lose datum. At one piece, the second-op route may be cheaper because the live-tool setup is not spread; at 100 pieces, the integrated cycle usually has room to recover it.
| Qty | Setup min (lot) | Cycle min (part) | Cost / part | Quoted / part | Lot price | Lead days |
|---|---|---|---|---|---|---|
| 1 | 123.3 | 4.1 | $227.32 | $295.52 | $295.52 | 9 |
| 10 | 123.3 | 4.1 | $31.61 | $41.09 | $410.90 | 9 |

What the material or process changes
Bar size, sub-spindle access, tool capacity and tolerance decide the practical path. If the part needs a deep side hole or a large flat, a VMC may still be the better machine. Outside finishing and inspection are not included unless named.
How to turn this into a firm quote
Quote both routes when the customer can accept either. Showing setup minutes and cycle minutes makes the choice defensible and gives the shop a clear trigger for moving repeat work onto live tooling.
Questions to settle before release
Check live-tool horsepower, bar capacity, cross-hole access, tool stations and sub-spindle support before promising the integrated route. For a second op, confirm the transfer datum and inspection method. A prototype may favor the VMC even when a production lot favors live tooling. Show both setup and cycle assumptions so the routing decision can be revisited after the first run.
For this live tooling vs secondary milling estimate, use the first production run as a check on this estimate. Capture actual setup minutes, cycle minutes, material weight and outside invoices, then update the shop rate or example part assumption that was wrong. That small feedback loop is more useful than rounding every quote upward. It also gives the next estimator a concrete explanation when the customer asks why a repeat job moved.
Pricing engine output for the stated Stainless 303 Swiss CNC turning example part
- • Material: Stainless 303; the US catalog stores its small-lot price and machinability factor.
- • Process: Swiss CNC turning; setup, machine time, deburring and inspection are generated from the example-part geometry.
- • Markup: 30% default US catalog markup; quantities are 1, 10, 100.
- • Fictional 2 in turned part from 1.5 in bar; one drilled end hole and one groove.
- • No outside finish, tax, freight, or customer-specific rate is included.
- • These are computed examples, not supplier quotes or market averages.
