From Sample to Series: How Contract CNC Machining Works

Process

A sound contract machining partnership starts with the right questions at the quotation stage. Here is the path from sample to series production, step by step.

When outsourcing a part, the biggest concern is whether the quality seen on the first sample will hold in series production. What reduces that concern is a process defined clearly from the start.

1. Quotation

The drawing, material, annual quantity and batch size are the basis of a quotation. If critical dimensions, surface treatments and special inspection requests are discussed at this stage, there are no surprises later.

2. Sample and first article approval

The sample should be produced on the machine and with the method that will be used in series production. Once the sample is approved together with its inspection report, that report becomes the reference for series production.

3. Series production

In series production the control plan used for the first article is applied unchanged. In-process measurements are recorded and a final inspection is made before shipment.

4. Delivery and traceability

Every batch should be traceable with its material certificate and inspection record. If a problem arises, it must be possible to find which batch and which material it came from.

At Novapex we run these four steps with the same discipline on every job. Send us your drawing or sample and let us plan the process together.
