Into the field of computer numerical control machine tools
CAM software software company. This can run all the PC software compatibility, call the NC system is open. PC communication, networking, e-mail (E-MAIL), voice, video and other functions, were used in the form of additional expansion cards to achieve. After the PC into the NC, when they need this capability, which can be purchased cheap and reliable add-on card into the expansion slot. FANUC display Seriesl60 in a MB, next to a video camera when the visitors approached the home, you can see in the CRT that 160MB of his own image has been inserted into a PC-class multimedia add-in card we found that many of the NC it is a new function,tory burch sale, are back in PC on the use of before. NC history from the point of view, essentially a dedicated computer numerical control system, many new technologies are made from the general computer area transplant, e to the delayed transplantation of about 5 to 8 years, PC into the NC, the to greatly shorten the lag. Because of these reasons, PC inroads into the NC. NC and PC Embedded PC there are two forms of NC because: (1) Some manufacturers believe that only one PC computing platform can not meet the requirements of NC while some manufacturers that, 386,486, PENTIUM (586) and other chips potential large, the key is whether the ability to make full use of it. 386 to the lower grade is that if the play well, can satisfy the mid-range and a considerable portion of the demand for high-end CNC. , (2) proction CNC embedded PC manufacturers that, PC's operating system, either existing DOS, the new WIN-DOws and WINDOWSNT, were designed mainly based on transaction processing, real-time poor} In addition, DOS can not perform multiple tasks. The other two requirements can only be performed without stringent real-time multi-task, therefore, can not directly control the machine tool and other manufacturers that can rely on the use of the original real-time PC timer interrupt to resolve. As to the implementation of CNC multi-task required, in the current difficult, most procts are not well resolved, and thus human-machine interface function has been weakened, however, do have a small number of our domestic resolved the better, not only strong man-machine interface functions, but also multi-channel (multi-process) control. The third type of proct does not include PC's reasons to be very influential 50 * from a manager of a company officer in the U.S. magazine, the views expressed by the author learned. (1) They think, Proction. (2) they believe that Once the form system, because there is no real time multi-tasking PC operating system, the machine is difficult to run other PC user software. That However,moncler cheap, the manager also stated, PC in the machine tool control is not without status, which in the future, control is by experienced and responsible for investment protection provided by the manufacturer,moncler jackets sale, the use of PC as a man-machine interface mass storage and communications, is still a viable option. seems to be understood as those in human-machine interface, large-capacity storage has been a considerable advantage. As technology and market inertia, into the PC without pressing their request, but in the into the PC necessary. PC access, but also to greatly simplify the proction of NC system, the cost of greatly reced,mbt shoes sale, making the machine tool factory-made system more easily. Thus, some U.S. manufacturing plants to low-cost machining centers to rece costs, the numerical control system from Outsourcing to self (see publication series on one). In short, whether it is embedded CNC PC, or PC into the CNC now PC, or into the future, PC is a general trend has been poured into the NC. foreign magazine, has been It was this phenomenon has been referred to as the birth of a new generation of CNC. that it is possible that NC has its own, the most far-reaching development.
