NUM applies on gear machine tool

The main function of system of numerical control of Num Power 10xH. Normally the outside figure of gear machine tool and the definition of each numerical control axes are as follows: Each axis of gear hobbing or roll flute defines X: Y of pillar shift axis: Cutting tool change moves axial Z: A of perpendicular and mobile axis: Main shaft head swings axial C: S of workpiece workbench runner shaft coming back: Runner shaft of hob or emery wheel coming back, also call main shaft to be in gear hobbing or process of roll flute loop, driven axis C is synchronous at drive shaft S, y and Z axis. U of axis of emery wheel nap: Rod of movement of radial of emery wheel nap (the deepness of cutting) , parallel the axial V at X axis: Rod of movement of axial of emery wheel nap, parallel is at the axis of X axis in process of emery wheel nap, driven axis V is synchronous at main shaft S. Graph 1: System of numerical control of Num Power 10xH of machine tool outline drawing is to be the numerical control system of numerical control gear-hobbing machine and development of machine of numerical control roll flute technically, its share 3 32 CPU are used at data operation and data processing, the synchronous function that will assure main shaft and workbench is compositive at interior of numerical control system. Among them the systematic resolution of C axis is extremely one of spending. Be aimed at the sort that machines gear, NUM developed a lot of corresponding gear cutting to secure a loop, introduce the main function that these gear cutting circulate simply now. 1.

Carry these G code, can realize bevel gear of such as straight gear, bevel gear, helix, beat the gear cutting of all sorts of types such as worm of gear of form gear, a flight of stairs, sector gear, worm wheel, different gear, if mill ages,still can come true (odd graduation) mix a variety of gear cutting functions such as groove. 2.

Of gear cutting respect additional CNC function. Pass the application of 20 old numerical control gear cutting, system of NUM numerical control accumulated rich experience in gear cutting respect, because system of numerical control of this Num Power 10xH is mixed in gear cutting,adjust a respect to bring very big convenient sex to the user. The indication of the information of a lot of gear cutting such as angle of head of tine number, hob, hob. User for love or money, can know any news of treatment gear conveniently. The hand in machining a process moves axial shift. The user is in gear cutting, can ask according to treatment constantly the hand is moved adjust each axes (this is particularly convenient to machining gear for the first time) , shortened greatly of gear cutting settling time, this function is particularly useful to gear cutting. Of the simultaneous error of main shaft and workbench detect. Trends monitors simultaneous error, can understand treatment precision at any time. Be opposite automatically the information in tine function process shows. CNC can hint be opposite automatically the each pace information in tine process (this information is open to the user) . Of the direction of rotation of C axis detect. PLC can be read take C axis direction of rotation (PLC can prevent an user write a mistake) . Buy oscillograph detects inside the simultaneous error of main shaft and C axis and main shaft and V axis. Pass inside buy oscillograph function, the user can see the dynamic error curve of C axis on CNC screen, can undertake a curve shrink put, OK and aleatoric lock decides numerical value to read the numerical value of need extraction place, detect to the user the error is very convenient. E parameter will show and revise parameter of gear hobbing function. Every E parameter has its corresponding meaning, and the parameter such as gain of OK and dynamic modification such as, to the machine tool debug and detect very convenient. Pass these additional function, went to the lavatory the numerical control system of gear cutting machine tool is debugged, shortened the auxiliary time of gear cutting process, and can be read through numerical control system read the news in gear cutting process timelily. These namely the biggest advantage of system of NUM gear numerical control. 3.

MMI man-machine interface because of gear cutting professional with oneness, we can ask to develop according to the specific technology of the user write the Chinese MMI interface that is aimed at gear cutting technically to replace original Num standard to operate an interface, this is very convenient to the process designing of the machine tool and operation. Handlers undertakes operating according to interfacial indication, very intuitionistic, concise. Graph 8: MMI man-machine interface pursues 9: MMI man-machine interface 2 4.

The open sex of powerful CNC and PLC function. System of numerical control of Num Power 10xH divides the open sex that took system of Num numerical control, outside flexibility, stability, be aimed at gear cutting, still have a few very special software functions. Dynamic Operator (dynamic operation) . The user can machine a function according to what what need, the dynamic program that writes oneself conveniently (scan every namely cycle executes an order) . Such users can write his interpolation program. Such as is not the treatment of the respect such as round gear. The system of numerical control of Num Power 10xH of user exchange area of NC and PLC because of PLC function compositive change, abounded the automation control of PLC function greatly. At the same time NUM provided the PLC that abound and perfects and CNC exchange area, it is the richest in system of all numerical control. Powerful polynomial interpolation. Very powerful polynomial interpolation function, can achieve 5 rank polynomial, use at writing the interpolation software with sophisticated function. For example the machine tool of YH2240 helix bevel gear of factory of machine tool of plain of the Qin Dynasty used this function. Pass the simple introduction of above function, system of numerical control of Num Power 10xH should be the optimal choice of gear machine tool. Machine of tine of machine of the machine of the gear-hobbing machine that in home we and machine tool manufacturer developed all sorts of set already successfully, roll flute, machine that insert tine, top gem tine, mill, gear shaving machine, transformed successfully again at the same time.
