Modern machine tools should have testing and calibration techniques

In order to prevent defects from occurring, companies must have the ability to edit process documentation and to ensure the accuracy of the machine's process. Both of these standards require the use of a club and laser interferometer to check the accuracy of the machine according to the recommended procedure. The purpose of adopting these standards is not to specify that the machine tool must meet a certain precision, but to find out what level of accuracy the machine tool can achieve. The written information of the part stipulates that the precision of the machine tool of the company must be able to produce qualified parts and set the precision benchmark in this place. Tested to let you know how high your machine can reach. As long as the machine can reach that precision benchmark, it has the ability to process.

Modern machine tools are equipped with testing and calibration techniques, and they are also able to provide this technology so that the shop can guarantee the accuracy and normal operation of the machine. More and more factories and large-scale workshops have their own laser interferometers and electronic equipment, while small factories can use commercial methods to obtain equipment and testing services at competitive prices through leasing through various channels. In fact, it is now possible to provide telescopic club detectors for any workshop, for the rapid detection of the machine tool, as long as the detection task can be completed within 15 minutes to maintain the machining accuracy of the machine tool. Using club detection can accurately evaluate the machine's geometric accuracy, roundness and stick/slip error, servo gain mismatch, vibration, backlash, repeatability, and misalignment of the scale. Some club software can provide specific error diagnosis according to ISO230-4 and ASMEB5.54 and B5.57 standards, then provide a plain English list, listing the sources of various errors in the order of the overall impact on machine tool accuracy. This allows machine maintenance personnel to deal directly with the problematic area.

Staged club tests keep up with the performance trends of machine tools. Preventive maintenance helps to plan before the machine deviates from the processing capacity. Industry generally tends to calibrate machine tools as needed, not as time. There is no reason to pull out a good machine that is engaged in production for maintenance. When something abnormal is found, it is still determined by the detection of the club and the parts produced. Production can continue during testing.

Can be used to automatically determine the location of parts, and then establish a working coordinate system, onboard detection can reduce the set up time, improve the spindle utilization, reduce the cost of fixtures and eliminate non-production processing access time. In complex part machining, it takes 45 minutes to debug fixtures, and the existing detection device only takes 45 seconds and is fully automated by the CNC. When starting to process a casting or forging, the inspection device can determine the shape of the workpiece, avoiding wasted time due to blanking, and can help determine the optimal cutting angle of the tool. The control in the process is the use of inspection devices to monitor the characteristics, size and position of the machine tool during the cutting process, and at the same time verify the precise dimensional relationship between the various features of each machining process in order to avoid problems. The probe can be programmed and the actual machining results of each stage can be checked by the program, and tool compensation can be automatically implemented, especially after roughing or semi-finishing.

Reference inspection is the comparison of part features with a dimensional template or a reference surface of a known location and size. It allows the CNC to determine the positioning gap and then generates an offset to compensate for this gap. Prior to critical machining, by detecting counterfeit templates, the CNC can check its own positioning for the known dimensions of the template and then program the offset. If the size template is installed on the machine and exposed to the same environmental conditions, reference testing can be used to monitor and compensate for the coefficient of thermal expansion. The result is a closed loop process that is not affected by the operator.
