The purpose measurement this thesis is to present the process of developing and manufacturing a measurement system with temperature compensation. The measuring system is used for final quality control of the dimensions of the product that comes from the CNC machine. It is indispensable for ensuring compliance of the product with dimensional values given in the plan. Tolerances are permitted only within the interval of measurement tolerances of each measurement characteristic. The ability to ensure process stability is a prerequisite for company success and competitiveness, especially in the companies that produce large series of products.
The measurement system consists of an industrial computer, which processes the data and displays it on the LCD display, an IR temperature sensor, which reads the temperature of the product and sends it to the computer, an input/output control unit for reading the status of the foot switch and a light indication for marking the plug gauges, inductive probes, which are located in separate measuring heads for measuring the diameter of the holes with the precision of a micron, and an analogue/digital interface Milimar X1715 by Mahr.
The measurement system with built-in software temperature compensation allows the user to measure the diameters of the holes with an accuracy of 1 micrometer, or 1/1000 mm, regardless of the temperature of the machined product.
