Below, be that numerical control generate gear grinding machines are example with the digital control system, the technical scheme in the embodiment of the invention is elaborated.
Fig. 2 a～2i is the configuration platform synoptic diagram of parameter configuration device in the embodiment of the invention.
Shown in Fig. 2 a～2i, the configuration platform 101 in the present embodiment comprises that gear parameter configuration platform 21, processing setting configuration platform 22, machining state configuration platform 23, emery wheel correction configuration platform 24, tangential admission configuration platform 25, the flank of tooth align configuration platform 26, stroke information configuration platform 27 and each Spindle Status configuration platform 28.
Shown in Fig. 2 a, the user can be earlier by configuration platform 101 input username and passwords, authentication by after successfully land, and select different configuration platforms according to configuration platform selector button 200.
Shown in Fig. 2 b, gear parameter configuration platform 21 comprises: a plurality of input interfaces 211, parameters of operating part such as the corresponding number of teeth, normal module, normal pitch pressure angle, helix angle, the face width of tooth, addendum coefficient, tip clearance coefficient, tooth depth modification coefficient respectively.
By gear parameter configuration platform 21, receive each parameter value value corresponding that the user determines at gear to be processed.A plurality of input interfaces 211 corresponding parameters of gear parameter configuration platform 21 are generally the independent variable of correlation parameter values such as gear involute urve, after the numerical value that has received all inputs, can give up really into completed information by 213 inputs of calculation of parameter button according to the user, affirmation user's input operation is finished, calls related function simultaneously the data of input are carried out functional operation.
For example, the numerical value 120 of input and 10 is the corresponding number of teeth and normal module respectively, the two is as the independent variable of reference diameter in the NC program, parameter scheduling unit 102 is with 120,10 and the parameter identification of corresponding expression reference diameter export to parameter arithmetic element 103, call corresponding function by the parameter arithmetic element and carry out functional operation, obtain operation result 1218.512, and with this operation result and the expression reference diameter parameter identification export to parameter scheduling unit 102, by parameter scheduling unit 102 operation result 1218.512 is exported to NC program run unit, realize renewal or assignment the value of reference diameter in the NC program.
Shown in Fig. 2 b, gear parameter configuration platform 21 also comprises a plurality of output interfaces 212, parameters such as corresponding transverse pressure angle, transverse pitch, reference diameter.These output interface 212 corresponding parameters are normally obtained through the mathematical operation of correspondence by the numerical value of input interface 211 input, parameter scheduling unit 102 can be according to the default output interface and the corresponding relation of parameter, the operation result of parameter arithmetic element 103 outputs is exported by corresponding output interface 212, made the user can know the value of these parameters.
If the numerical value of input or exceed each limit range of numerical control generate gear grinding machines correspondence according to the operation result that obtains of numerical value of input then can be by parameter scheduling unit 102 by the miscue information of gear parameter configuration platform 21 to the user prompt correspondence.
For example, the range of the column of numerical control generate gear grinding machines is 2 meters, and promptly the ultimate range of column gear centre to be processed relatively is 1 meter.In this case, the product of number of teeth value and modulus value must be smaller or equal to 1000.And if input be 150 with number of teeth value corresponding, with the modulus value corresponding be 10, then because the two product is 1500, parameter scheduling unit 102 will be not enough to user prompt column stroke by gear parameter configuration platform 21 and the miscue information that can't process.

The user can also set the grinding speed of each circle according to actual conditions.As first corase grind correct grinding again, set grinding speed according to the principle order from big to small that is complementary with stroke speed again.
Currying work is every then being the influence that indexs such as tooth-formation of gear, teeth directional, smooth finish are not subjected to the roughness of the emery wheel conical surface when guaranteeing grinding worm, and emery wheel is finishing regularly.By setting the number of teeth at interval, i.e. grinding teeth groove number, grinding carriage can periodically return to trim locations, emery wheel is repaired according to default trim amount by trimming devices such as for example diamond pens.Like this, just guaranteed the precision of grinding.
According to the actual process demand, determine the feed rate of the processing number of turns and each circle, and once import value corresponding, can realize that the processing number of turns different in the process adopts different feed rates.
Because factors such as emery wheel material, size, workpiece materials, grinding speed must be rationally constant.Behind the required grinding speed of actual conditions setting, as 35m/s, the rotating speed of automatic setting emery wheel is to keep grinding speed constant behind the digital control system detection grinding wheel diameter.
The spark amount that the user produces in the time of can also be according to grinding judge emery wheel and contacting of workpiece whether suitable set automatic grinding when initial liquid coolant whether open, also can in grinding process, open; And after closing the cooling instruction issuing, liquid coolant only just disconnects after emery wheel and workpiece disengaging, like this, can prevent that liquid coolant from stopping to cause flank of tooth burn suddenly.
