  Manual quote vs CNC NC quote

Most machine shops do not lose time on the cutting speed calculation. They lose it before the price exists. A 2D PDF arrives, an estimator reads it by eye, types geometry into a spreadsheet, then walks to the floor to ask whether the 5-axis schedule can take the job. Two days pass and nothing has been machined yet.

A quote is mostly data movement. Someone has to translate a drawing into a part number, a material, a tolerance callout and a machine choice. Every manual step in that chain adds an error chance and a waiting period, and the waiting period is what customers feel.

NC quoting starts from the file that will eventually drive the machine. The same CAM toolpath that cuts the part generates the cycle estimate. One data set, two uses, no re-typing. That is the whole idea behind how CNC NC reduces quote time by 90%.

The floor check does not disappear. It changes form. Instead of a phone call, the estimator sees machine load, tool inventory and fixture status in the same view as the geometry. The question gets answered in seconds, not shifts.

NC is not a pricing trick. It means the numeric control program, the toolpath set that runs on the machine, is built first and priced second. The estimator does not guess a cycle time. The software posts the toolpath and reads the run time back.

That changes the order of operations. In a classic shop the price comes before engineering. In an NC-quoted shop, light CAM work happens at quote stage. A 5-axis part might get a rough toolpath with a Ø12 mm end mill, three passes, and a stated stock size. The number that comes out is close enough to commit to.

The 90% figure refers to elapsed time from a complete file package to a released quote. At GreatLight that window is quotation and free DFM analysis within 12 hours. It is not a claim that every quote takes minutes. A complex housing with 40 toleranced features still needs an engineer to look at it.

Two conditions must hold for the reduction to appear. First, the customer sends a 3D model, not only a PDF. Second, the shop has a standard material and tool library so the software can resolve features without human naming. Remove either one and the clock resets.

Speed is a property of the input, not of the shop. If a part has no defined datum scheme, an automated quote will price a geometry that cannot be inspected. The quote arrives in hours and the part fails first article. That is worse than a two-day quote.

Thin-wall and deep-cavity parts are the classic failure case. A 1.5 mm wall on a 6061 bracket may need multiple light passes, stress relief, or a different stock orientation. Software that reads only volume and feature count underestimates those by a wide margin.

Some jobs should be quoted slowly on purpose. First articles for aerospace, implantable medical components, and any part with a true position callout tighter than ±0.005 mm deserve an engineer's hour. Paying for that hour is cheaper than a scrapped lot.

There is also a floor on honesty. If the shop quotes fast and then discovers a fixture is needed, the schedule moves. A quote that takes 12 hours and holds is worth more than one that takes 2 hours and slips.

The fastest quotes come from packages that answer questions before they are asked. A STEP file plus a drawing with material, finish and critical tolerances covers most of it. Add the target quantity and the deadline and the estimator rarely needs to email back.

Quantity matters more than most buyers expect. One prototype and a 10,000-part run use different processes. GreatLight has no minimum order quantity, so both are quoted, but the run strategy differs: single-setup 5-axis for the prototype, fixtured multi-axis or mill-turn for the run.

Material choice sets the baseline. Aluminium 6061-T6 cuts fast and quotes fast. Inconel and TC4 need slower feeds, more tool changes and sometimes a different machine. If the drawing says Inconel but the function allows 17-4PH, saying so at quote stage saves a revision cycle.

Finish is the quiet cost driver. As-machined at Ra 1.6–3.2 μm is one pass. Bead blasting, anodizing or hardcoat adds outside processing and a handoff. Naming the finish on the RFQ keeps that handoff inside the original quote window.

A fast quote is not software alone. It needs a machine list that the quoting engine can trust. Cycle times are only accurate if the tool library matches the tools actually loaded in the spindle, and if the post-processors match the real machine kinematics.

With 16 simultaneous 5-axis machining centers, 12 four-axis mills, 27 three-axis machines and 16 mill-turn centers, the routing space is wide. A Ø400 mm rotary table opens one set of options; a 4,000 mm maximum processing size opens another. The quote engine has to pick between them the way a planner would.

Standard work is the second requirement. If two estimators price the same part differently, the fast quote is just a fast guess. GreatLight keeps a shared library for material removal rates, tool costs and setup times so the output is repeatable.

Inspection has to be planned at quote stage too. 100% inspection before shipment is the default, and reports are available on request. Quoting without that step in the plan creates a gap between the price and the shipment.

The quote is only useful if the schedule can absorb the job. At GreatLight, production can start within 24 hours of approval and parts ship in 3–5 days. A quote that arrives in 12 hours but cannot be scheduled for two weeks is not a 90% improvement.

That is why the machine load view sits next to the quoting view. The estimator is not guessing whether a 5-axis center is free. They see the queue, the fixture status and the material stock position before releasing the number.

Historical late-delivery probability is below 2%. That figure comes from the same data discipline. If the quote is built from the real toolpath on the real machine, the promise is built from the same source.

The loop closes on repeat orders. Once a part has run, its actual cycle time replaces the estimate. The next quote for that part is faster and more accurate than the first, which is where the compounding benefit shows up.
