Machining characteristics of CNC machining equipment CNC machining equipment has the characteristics of complex equipment, high degree of automation and high processing precision. For example, the most commonly used CNC machine, CNC milling and machining center in CNC machining equipment is taken as an example. The most commonly used machining center is the boring and milling machining center. In addition to the addition of the tool magazine, the machining center has the same structure as the CNC milling machine. Therefore, the CNC milling machine and the machining center are classified into one category. The correlation between the parts processed by CNC and CNC milling (including machining centers) is not significant. The CNC car is mainly used for machining rotary parts such as shafts and disc sleeves. It can automatically complete the cutting process of inner and outer cylindrical surface, cone surface, arc, thread and Other processes through program control, and perform grooving, drilling, expanding and reaming. Holes and other work. CNC milling (including machining centers) has much larger processing objects, mainly including: (1) box-type parts, which have more than one hole system, and have internal cavities. These parts are in CNC milling (machining center). ) Processing, one-time clamping can complete most of the process content. (2) Shaped parts, that is, irregularly shaped parts, most of which require point, line and surface multi-station mixing processing. At this time, the characteristics of CNC milling (machining center) process concentration can be fully utilized, and reasonable process measures can be used once or Secondary clamping, complete multiple processes or all processing content. Disk, sleeve, plate parts, the end face of this type of parts has a distribution hole system. The curved sleeve parts of the curved surface should also be processed by CNC milling (machining center). CNC milling (machining center) can also play a unique role in complex surface machining and special machining. The ordinary lathes that can be processed by CNC lathes can also be processed. However, most of the ordinary milling machines that can be processed by CNC milling machines can not be processed. Therefore, it should be given priority in the comprehensive machining enterprises that have both shaft parts and boxes and cavity parts. Choose a CNC milling machine. It can be seen that in the integrated machining enterprises, the importance of CNC milling machines (machining centers) is greater than that of CNC lathes, so CNC milling machines (machining centers) should be given priority in the layout. The layout method of CNC machining equipment chooses the production mode of modern manufacturing enterprises to shift from mass production to more flexible medium-volume custom production mode. This requires CNC machining equipment to be more flexible in all aspects. According to the processing characteristics of CNC machining equipment. The specific method is divided into two steps: First, the subunit is constructed, and the workshop is divided into subunits according to the functional grouping rules. Firstly, the subunits are arranged in the plane of the shop floor. When the subunits are laid out, the numerical control milling machine should be given priority in logistics. The machining center); the second is to layout the same function devices in the subunit. The implementation method of the functional unit layout method According to statistics, in the processing of a mechanical product, the waiting time reaches 90% to 95%, and the time for real processing of the product is very small. The time of logistics flow in the workshop is one of the main factors affecting the processing efficiency. Calculation method: Distributed genetic algorithm can be used to calculate with MATLAB software. The calculation parameters needed in the genetic algorithm need to be determined in the calculation. Because it has great influence on the calculation of genetic algorithm, it needs to be tried and determined repeatedly.
