When quality issues need to be seriously considered, calibration and compensation will directly affect the cycle time.. A machine tool within the precision index range can work at high speed while maintaining machining accuracy. Calibration allows for online detection of workpieces, saving time for the workpiece to move back and forth between the machine tool and the coordinate measuring machine. In addition, regular calibration can also be used to predict whether the machine tool is about to deviate from the accuracy index. When using an online inspection bending machine, replace the tool with an appropriate measuring head to measure the size of the workpiece. The spatial positioning error can be listed as an error table or compensation table to enable the software to correct the position of the measured probe. By using spatial error correction, the geometric and positioning errors of the machine tool itself can be eliminated, providing accurate dimensional measurements. Therefore, meeting the accuracy requirement of 4:1 gauge enables CNC machine tools with spatial error compensation to have the same high-precision function as coordinate measuring machines. The trajectory of the target being measured is not a straight line, and its lateral movement is significant. Conventional interferometers cannot perform these measurements because such large lateral movements are not allowed. Single aperture laser interferometers such as Laser Doppler Displacement Meters are not affected by large lateral movements. Using a flat mirror as the target to be measured, movement parallel to the mirror will not transfer the laser beam, nor will it change the distance from the light so

urce. After refining the above repeatable basic steps, acceptable performance and accuracy levels can be determined. In addition, it is necessary to measure and establish the reference line of the machine tool. The measurement of machine tools is regular and carried out at specified time intervals. After analysis, combine maintenance and repair forecasting with production scheduling. With the advancement of technology, the cost of laser calibration equipment has been greatly reduced. For example, Optodynes products (bending machines, shearing machines) in the United States do not require professional metrology personnel or external services, and the downtime of machine tools has also been greatly reduced. A mechanic who has received one day of laser calibration training can complete a spatial measurement of 1 cubic meter of machine tool in half a day. The software can automatically write a compensation table and upload it to the controller of the machine tool Previously, operating laser calibration instruments required professional metrologists. It is necessary to open the machine cover so that optical components can be adjusted on the worktable, spindle, and independent tripod. The process of spatial calibration takes several days, depending on the size of the machine tool. Therefore, when the workpiece is measured within the tolerance range by a coordinate measuring machine, spatial calibration becomes less necessary. Using a bending machine with spatial detection function to detect workpieces during the machining process can greatly reduce cycle time and improve machining accuracy. In the aerospace industry, online detection has not been developed because detection on the same machine tool used to process workpieces c
