What benefits can OMV bring to users? First of all, through the above two states of using OMV or not using OMV, we can see that the biggest bright spot is to improve the productivity and efficiency of the process. Imagine that it is no longer necessary to manually measure and change to CNC automatic measurement, which saves time; during the process, you know whether the next step needs to be executed or reworked, and you don't have to find the error in the final measurement and can't correct it. The productivity has increased.
In addition, the use of OMV also reduces the cost of fixtures, maximizes investment savings, and gives you the confidence to deliver the finished parts to the final inspection. On-machine inspection monitors the quality of parts at each stage of the process. At a lower cost, detect errors as quickly as possible and correct them more quickly.
For example, it can detect the exact number of burrs that have been left after the part has been roughed, avoiding the occurrence of these errors until the end of the entire machining process.
Similarly, it can detect the degree of damage caused by any error, such as accurately assessing the amount of tool wear, and immediately make a judgment as to whether the part can continue to be processed within the tolerance range or to be disposed of.
On-line testing of machine tools is most beneficial for manufacturing companies that currently do not have the ability to detect. Most advanced machining machines nowadays are designed to assist in the assembly of parts, or are equipped with original detectors or have improved inspection capabilities. With the OMV version of PowerINSPECT, the same machine now requires the little extra cost to complete the entire inspection. It can program all the detection sequences in an offline state, and the processing process is not interrupted as much as possible to ensure the continuity of the processing. The on-machine inspection system saves a lot of machining time by monitoring the quality of the machined parts at every stage of the process. On-machine detection can detect any errors that occur during processing as early as possible and correct them as quickly as possible, and at a low cost.
For example, it can detect the actual margin left after each process, and this function has obvious advantages over waiting for all the machining processes to end.
Let's take a look at the performance of OMV in the manufacturing process!
Figure 1 shows the traditional manufacturing process without OMV. When the machined part is delivered to the CAM system for numerical control programming through the CAD model, the machining is started. Once the machining is complete, the part is moved to a three-coordinate measuring machine for final inspection based on the original CAD data. If the measurement is acceptable, the processing is completed. If the measurement is unqualified and there is no on-machine detection, if there is an error on the CMM after the part is processed, the part must be reloaded back to the machine. Before the modification is processed, the workpiece must be re-clamped. This process is for any part. It is a time-consuming and laborious task, especially for large and heavy-duty parts, such as stamping dies for body panels. In addition, if there are any errors in the re-positioning process, some new errors will be generated on the workpiece, which in turn will lead to product inspection and re-processing. "Trouble, inefficiency, time-consuming and costly", this is the conclusion!
If the OMV system is used, the PowerINSPECT OMV detection software continuously interrupts the machining process and monitors the state of the machined parts at any time during the machining process. Errors in the machining process are detected and resolved in time. It is also very beneficial to realize the on-line inspection of CNC machine tools for those customers who require independent product inspection reports. By directly detecting on the CNC machine tool, the error can be found and modified in time to avoid the occurrence of errors until the product is submitted to the tester. This ensures that the parts are processed. Delivered to the customer in one go through the final inspection of the three-coordinate measuring machine.
