What are the advantages of glass CNC machining centers?The glass CNC machining center has the characteristics of short development cycle, small development workload, rich functions, powerful algorithms, and strong expansibility. Conducive to the long-term interests of the enterprise. In order to reduce costs and improve product competitiveness, a PC-based full-software glass CNC machining center system with a general controller as the control platform. This paper systematically analyzes the CNC glass CNC machining center from three aspects: mechanical composition, electronic control module and technological process. CNC glass CNC machining center is a typical five-axis four-linkage equipment. The gantry axis is controlled by two servo motors. The gantry synchronization problem needs to be considered in the system design. Using the unique mirroring function of the AMC controller, the gantry slave axis is mirrored to the gantry spindle, thus solving the gantry synchronization problem. Aiming at the process characteristics and functional requirements of glass CNC machining center, based on QT platform and using C++ programming language, a PC-based full software system software architecture is designed. Software modularization, divided into HMI (human machine interface), soft PLC, NC kernel. HMI includes main interface, graphic display, parameter setting, system maintenance, tool management, status display and other functional interfaces. The soft PLC is responsible for the IO operation of the entire system. The function of soft PLC is to facilitate different manufacturers to define functions according to their own needs and to facilitate customer expansion. The NC kernel is the core of the entire system and is responsible for the processing program control and data interaction of the system, and is generally composed of multiple threads. In order to solve the problems of speed oscillation and low processing efficiency caused by continuous small line segments in the process of glass CNC machining center, a forward-looking algorithm based on acceleration and deceleration before interpolation is proposed. The speed is reasonable, and through simulation experiments, this forward-looking algorithm is feasible. Glass CNC machining center parts are very important optical parts, commonly used are parabolic mirrors, hyperboloid mirrors, ellipsoid mirrors, etc. Glass CNC machining center parts can obtain unparalleled good imaging quality of spherical optical parts, and can correct various aberrations in the optical system, improve imaging quality, and improve system recognition rate. It can use one or more aspheric surfaces. The part replaces a plurality of spherical parts, thereby simplifying the structure of the instrument, reducing the cost, and effectively reducing the weight of the instrument. Glass CNC machining center parts are also widely used in military and civilian optoelectronic products, such as photographic lenses and viewfinders, TV cameras, zoom lenses, movie projection lenses, satellite infrared telescopes, video recorder lenses, video and audio CD read heads, barcode read heads, Fiber optic connectors for fiber optic communications, medical equipment, etc. Finally, after completing the design of the glass CNC machining center software, the actual processing test is carried out on the glass CNC machining center machine. From processing simple lines, arcs and rectangles to processing complex graphics, the same glass products are processed and compared through the current CNC effect, and the same processing effect is obtained. |
