System of numerical control of lathe of T560_T open mode controls card and composition of industrial control computer by PMAC-LITE four-axle motion, its software cent is go up a machine (PC) and leave an opportunity (PMAC) two parts. Go up an engine is main the administrative function of the system that finish, be like the implementation of man-machine interface, treatment status shows, copy comes true really, parameter edits, parameter configuration, program document edits, port condition monitors the work such as the diagnosis with breakdown. The logic that the software that leaves an opportunity basically is the athletic control that realizes a machine tool and signal is controlled. PTALK part is go up a machine and the communication module that leave an opportunity. Its structure is shown 1 times like the graph. Graph system of numerical control of KT560_T of plan of 1KT560_T software structure is the FONCS that opens numerical control limited company in Shanghai the compose on the foundation of platform of development of system of general numerical control builds. The used OOP design idea with sufficient FONCS combined industry to control the characteristic of the configuration software of the domain. The user can pass the development tool of FONCS, undertake visible configuration to software function module, the functional package that from inside module library v needs perhaps deletes needless component. The result that the development tool of FONCS configures to the system maintains presence in file of a database, when in running an environment, FONCS is started, meeting ground the information in this database, trends generates user interface (graph 2 with graph 3) . User have the aid of at a such mechanisms, the machine tool that can be oneself inside short time is custom-built appropriative controls a system. Graph the interfacial structure of 2KT560_T pursues 3 systems interface (advocate interface, hand is moved interface, automatic interface and diagnostic interface) each interfaces of the system undertake switch through systematic menu, editor of a menu was offerred in KT560_T (graph 4) , the user can define the exterior of the structure of menu and menu pushbutton oneself through this tool, reflected open sex of the system adequately. Graph in the process that 4 menu editor is using numerical control machine tool, the examination method of numerical control program is one of main factors that affect productivity, desired result of numerical control course has 3 kinds of methods commonly usedly, it is by the editor personnel examines NC code, data; 2 it is to be on the machine tool " with pen acting knife " , imitate machines a picture to give cutting tool contrail; 3 it is to use the computer to come the opposite campaign of simulation cutting tool and workpiece will undertake checking. Apparent take time of before two kinds of methods, arduous, increased the holding time of the machine tool; And the 3rd kind of method is intuitionistic, swift, can reduce the workload of process designing personnel, raise utilization rate of numerical control machine tool. The dynamic and three-dimensional emulation function in KT560_T, can emulate the turning process of lathe, have sense of reality. Copy of three-dimensional numerical control is numerical control machine tool really the map in fictitious environment, theory of numerical control of collect production technology, machine tool, CAD (CAD) , CAM (CAM) , build model and emulation technology at an organic whole. Here the cutting tool in fictitious environment undertakes fictitious cutting to workpiece, the validity that can check numerical control order, rationality, be evaluated to machining the actor bad of plan to make and optimize; Achieve shorten product treatment is periodic, reduce the cost, goal that improves quality. The emulation of KT560_T uses means of real time animation, make a semifinished product above all, build the each frame of animation according to the material purify rule when machining next. Three-dimensional emulate through three-dimensional demonstrate the window to show go up in screen. In automatic module and editor module, can be in of the file when open and be being saved, undertake fast emulation demonstrates. Graph 5 demonstrate to machine the dynamic and three-dimensional effect when a bowling bottle. Graph 5 three-dimensional the systematic parameter that demonstrates system of KT560-T numerical control governs a function, can satisfy the requirement of open sex and flexibility, security and dependability at the same time. The parameter that involves as a result of numerical control machine tool is very much, the parameter that the numerical control machine tool with same even different kind has the numerical control machine tool of different type to differ severally, this brought inconvenience to parameter management, ask parameter management module has very big flexibility and open sex, when change be producinged by administrative parameter, parameter management module can be self-reacting the change of generation, can be opposite namely the addition of parameter, decrease, the change of the type government that has trends. KT560_T offerred a parameter to design software tool (software parameter interface sees a picture 6) , allow a system to make definition of manufacturer proper motion and editor system parameter.
