What are the constraints of intelligent manufacturing of precision parts processing? Precision parts processing With the increasingly clear division of labor, enterprises no longer pursue only big and comprehensive, but pay more attention to their core capabilities. If you focus on product development and market development. Then this production system over will form some specialized manufacturers especially some precision industries, the need to produce some of these enterprises. In the face of the market, this kind of enterprise product variety, small scale, many products are even single piece production. In this case, the production cost and efficiency depend on the quality and ability of the staff. Such enterprises are constrained by more factors when they engage in smart manufacturing.
First, the products are diverse and complex, and it is difficult to complete the production with some simple equipment, which requires complex process flow. This will lead to a long and complex production line. Therefore, a more complete equipment function or more intensive process is needed. Therefore, its equipment tends to horizontal machining centers, five-axis machine tools, composite machines and other equipment.
Second, precision parts processing will have higher requirements for talent; many of them belong to single-piece small batch production, which needs to be improved by processing application technology to achieve product processing. Therefore, in order to process high quality products, more people need to understand the processing, process and function of the product itself.
Third, due to the complexity of its products in small batches, online quality control of the product processing can be achieved so that the product can be inspected in the process, or to a certain extent, the product is processed to confirm and correct the coordinates, and the product can be confirmed before going off the line to achieve product quality control. In order to avoid the product does not meet the requirements of multiple clamping before processing.
At present, due to the high precision of parts processing, with high product accuracy, complex parts, small batch characteristics, greatly limit the realization of our automation. Even if we could automate, the cost would be very high. Therefore, the best solution for such products is to work with people and machines. In terms of arrangement, try to use the FMS line for wiring. In the FMS line, a zero-point positioning system is combined with a special fixture to clamp parts outside the line for automatic in-line machining and production.
It improves the automation and flexibility of the part processing process, and also provides the utilization rate of our production line. In addition, the processing of precision parts requires strict control of the external environment. Since we are machining products, the factor that has the greatest impact on accuracy is temperature. On the one hand, temperature affects the accuracy of our own machine tools, and on the other hand, it affects the deformation of the material. The theoretical data is not consistent with the actual data. Therefore, the machine itself needs to be equipped with various temperature control means, such as adding chip fluid temperature control, spindle and screw for temperature control, etc. In addition, there is a need to establish a constant temperature workshop for such production lines. Minimize the influence of temperature on product processing accuracy.
