Control And Measuring Instruments

Serial production of details for the construction of cars, machines or household appliances is associated with the need to maintain a high level of dimensional precision. Especially in the case of machines and components in motion, their parts must be perfectly matched so that they interact without causing friction and accelerating the rate of wear. That is why systematic CMM measurements performed with the use of special coordinate measuring machines are so important. These machines are equipped with three measuring systems enabling simultaneous measurements in the XYZ coordinate axes. An additional element is a probe that allows you to locate the surface of the measured element. CMM coordinate measurementsthey take place automatically and are made with the use of CNC technology, also commonly used in precise CNC machining . Such production tests are characterized by very high accuracy and are not exposed to errors resulting from human physical limitations or his subjective approach

In the vast majority of plants, especially in the automotive, aviation and machine industries, one of the basic requirements is QA - Quality Assurance . This in turn requires reliable and permanent quality control (QC ). Quality assurance and its control are often related, although they are defined differently. The differences between quality assurance and quality control Quality assurance activities and responsibilities usually cover virtually the entire quality system, while QC is a series of quality control activities. In addition, elements of the quality system may not be specifically covered by QA / QC activities and responsibilities, but may include QA and QC. Referring to the above definition, as well as taking into account the industry in which we operate, we come to an important issue, i.e. measurement control. Measurement control The scope of measurement control includes many ways and methods, which often requires devices individually

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.
