Dispatch of net of machine tool of Chinese numerical control: Cent of online testing system is numerical control machine tool two kinds, one kind is call directly basic grand program, and do not assist with the computer; Another kind wants him to develop grand library, have the aid of assists process designing system at the computer, generate at any time detect program, in transmitting numerical control system next. The online testing system of numerical control machine tool is comprised by software and hardware. Hardware part divides composition by the following normally: (1) noumenon of machine tool of 　 of 　 of machine tool noumenon is implementation treatment, detected foundation, its job component is the part that implementation wants to move basically, the precision of its drive disk assembly is affecting treatment, detected precision directly. (2) at present numerical control machine tool uses 　 of 　 of numerical control system commonly system of CNC numerical control, its are main the characteristic is operation of input memory, CNC Machining, interpolation and machine tool all sorts of control functions pass a program to come true. Interface equipment connection can be passed between the computer and other unit, when controlling object or functional change, need to change software and interface only. CNC system is mixed by memory of the processing central commonly composition of input output interface, central processor is comprised by memory, arithmetic unit, controller and bus line again. (3) servo 　 　 the main component that servo is numerical control machine tool, the control of feed position servo of machine tool of numerical control of implementation of in order to and main shaft rotate speed (or the position) servo control. The function of servo is the precision of treatment of decision machine tool, main factor that measures quality of precision, surface and manufacturing efficiency. (4) measure systematic 　 　 to measure a system to the contact touchs hairdo to measure head, signal to transmit system and data to collect a system to comprise, it is numerical control machine tool the crucial part of online testing system, immediate impact is worn online detected precision. Among them crucial part is measure a head, use measure a head to be able to undertake in machining a process dimension is measured, modify machine program automatically according to measuring an outcome, improvement machines precision, make since of numerical control machine tool machines equipment, hold concurrently again measure some kind of function of machine. At present commonly used Leinishao measures a head, it is the product that British thunder Ni Shaogong manages, they are used at numerical control lathe, machining center, on the machine tool of most numerical control such as numerical control grinder, private plane. Measure a head to be able to be divided by the function detect for workpiece measure head and cutting tool to measure a head; By signal transmission means can be divided for hard line join type, induction type, optical type is mixed radio type; By the contact the form can be divided measure to the contact is measured and be not a contact. The user can choose proper configuration according to the specific type of the machine tool. (5) online testing system uses 　 of 　 of all of computer science department the computer undertakes metrical data collect and processing, detect of numerical control program generate, detect of the process emulate reach wait for a function with communication of numerical control machine tool. Online testing system considers run the software such as current and popular Windows and CAD/CAM/CAPP/CAM and VC++ , and reduce the analysis that measures an outcome and computational time, use the computer of Pentium level above commonly. Belong to lathe of numerical control of CK6132-B of dragon machine tool for example, provide the system of WA-2000S numerical control that Gao Ke relies on. This machine tool uses Electromechanical unifinication design, lathe bed uses tall hardness project plastic and purificatory and into, employ 4 worker worker automatic circumgyrate tool carrier, be opposite through process designing all sorts of dish kind, axis kind the cutting treatment that waits for plastic spare parts to complete the work such as face of face of cylinder of inside and outside, taper seat, circular arc, whorl automatically, can have the job such as grooving, bore.
