Quality control is conducted at two levels and is adapted to the individual needs of customers. The first stage of control is shop-level inspection at the individual tools. The technical control department is independent from manufacturing. It represents the second stage of control, and also defines the conditions for measurements conducted in the first stage. Measurement conditions are defined in the measurement plan that determines the specific dimensions to measure, the frequency of measurements, specific gauges to use, and how records are maintained.
The Technical Control department, led by the Quality Manager, defines the measurement plans, documentation for initial sampling, or the entire set of documents required per specific requests. Typical requirements include 3D measurement equipment reports and the traceability of production and measurement data. All measurements are recorded using standard gauges and electronic data transmission to a PC, which ensures that no errors occur when manually entering values.
Statistical assessment of measurement data (Cpk, Cmk) has become a more common request. Our new Q-STAT and Q-DAS software from Hexagon meets this very purpose. A proven measurement method is to compare the 3D model with the real-life product and subsequent graphical assessment.
Good quality machining would not exist or be able to produce quality products without quality measurements. That is why we place so much emphasis on quality management. We have held the ISO 9000 quality management certificate since 2003.
