Costing an ultrafast process means costing the alternative it replaces
Ultrafast machining is expensive per hour and per part. It competes by removing operations, scrap and qualification risk rather than by being cheap.
An ultrafast micromachining system has high capital cost, moderate running cost and low throughput compared with most alternatives. Costed on machine hours per part, it rarely wins. The applications where it is established won on a different basis.
Where the savings come from
Eliminated operations. A process producing no recast layer removes the recast removal step, with its tooling, its cycle time and its own tolerance stack. A process producing no burr removes deburring.
Reduced scrap. Where the alternative damages a proportion of parts — cracked glass, delaminated coating, burred electrodes — the scrap rate applies to the full accumulated value of the part, which in electronics or medical devices can be substantial by the time it reaches this operation.
Avoided qualification risk. In regulated production, a process whose thermal damage must be demonstrated to be within limits carries a testing burden. A process with negligible thermal damage may reduce that burden.
Enabled geometry. Where nothing else produces the feature, the comparison is not cost but feasibility.
Where the comparison is done wrong
Comparing machine rates. An ultrafast system's hourly rate against a mechanical process's hourly rate ignores everything above, and it consistently favours the mechanical process.
Comparing on a simple part. Ultrafast rarely wins on parts that a conventional process handles well. Evaluating it on such a part and concluding it is uneconomic is correct for that part and says nothing about the parts where it belongs.
Ignoring accumulated value. Scrapping a part at the last operation costs everything invested in it, not the material.
The honest summary
Ultrafast processing is a premium process that pays where thermal damage from a cheaper process causes a downstream cost — an extra operation, a scrap rate, a qualification burden, or an outright inability to make the part.
Manufacturers who evaluated it on that basis generally found a clear yes or a clear no. Those who evaluated it on machine hourly rate generally found a no, sometimes for parts where the answer should have been yes.
