Definition Of Quality Control Processes

The production of parts for machines and devices, the work of which requires very high precision and matching of each element, must undergo strict quality control. One of its elements is the dimensional compliance test, so important, for example, in the case of elements of bearings, gears or motors. Therefore, control and measurement instruments are an important part of the equipment of every company that carries out such serial production . These include, among others, coordinate machines with which CMM coordinate measurements are made . The precision of these machines' operation creates much greater possibilities than those offered by traditional control instruments - calipers, length gauges, micrometers, etc. The offer of the ZETEK company includes modern control and measuring instruments such as a coordinate measuring machine or a portable measuring arm. Thanks to its mobility, it allows you to take measurements anywhere, outside the laboratory or production hall

Although control and measurement devices (tests) should and most often are used in a very safe way, they still require cyclical measurement control and regeneration and possible calibration in order to obtain the required measurement accuracy, reliability and repeatability. Ensuring the stability and certainty of quality control - in this case control measurements - translates directly into the quality of manufactured parts and related possible complaints, repair costs and / or service actions. In order to avoid such situations, it is necessary to take care of the impeccable condition of the measuring instruments. Therefore, both in the event of a fault on the gaugecaused by a mechanical factor, related to an accident or an unfortunate coincidence, as well as in the case of the approaching time of cyclic calibration, which, depending on the conditions and intensity of use of the test, should

The certification of gauges is based on checking that the instrument maintains the prescribed measurement tolerances and MSA processes that confirm the stability of the measurement process of the gauge used in different conditions and by different people. Tests and control and measurement devices undergo the process of checking the current state, and then we carry out the calibration process and recertification. We carry out the certification and calibration process of the gauges in accordance with the procedures resulting from ISO 17025 , which confirms the credibility of our work. At the client's request, we perform work in accordance with the requirements and processes resulting from the individual features or parameters of a given measuring instrument. Calibration of the gauges Calibration is an integral part of the construction and production processes of control and measurement devices and gauges, and is also used during service or repair work.

The production of complex shaped elements formed from sheet metal requires the use of very precise tools. Designing them with the use of specialized programs such as CAD and supplementing with the visualization of the finished stamp is not always sufficient to guarantee a satisfactory effect. Therefore, a stamping simulation is essential to make sure it is correct before introducing progressive dies or cutting tools into production . Authors and PAM STAMP is the software we use to perform such a simulation. Both programs are a perfect solution for companies wishing to design and launch a new product. PAM STAMP stamping process simulation enables initial part feasibility assessment, tool design and full verification simulation. We can predict how the material will behave during each pressing phase. This solution makes it possible to optimize the process so that the pressed detail does not show any tendency to cracking, folding or excessive springback.
