the method for grinding embodiment of numerical control compound grinding machine
According to the utility model embodiment, provide a kind of method for grinding of numerical control compound grinding machine.As shown in Figure 2, the present embodiment comprises the following steps:
Step 100: in first passage, call circle end face combination processing technology, perform step 101;
Step 101: in first passage, operation circle end face combination processing technology, performs step 102;
Step 102: judgement, when whether prepass is first passage, if so, performs step 103; Otherwise, exit circle end face combination processing technology;
Step 103: judge that whether real-time interrupt signal is abnormal, if so, perform step 111; Otherwise, perform step 104;
Step 104: the right bistrique processing technology of Automatically invoked second channel, performs step 105;
Step 105: operation second channel right bistrique processing technology, perform step 106 with step 109;
Step 106: call and move left bistrique processing technology, perform step 107;
Step 107: in the first passage of being controlled by the first axis servomotor X1 and the second axis servomotor Z1, left bistrique starts cylindrical grinding, performs step 108;
Step 108: wait for or confirm that cross grinding technique finishes;
Step 109: in the second channel of being controlled by the 3rd axis servomotor X2 and the 4th axis servomotor Z2, right bistrique starts face grinding, performs step 110;
Step 110: the sign that output end face grinding finishes, performs step 108;
Step 111: interrupt cylindricalo grinding technique and cross grinding technique, binary channels is resetted, perform step 112;
Step 112: left bistrique and right bistrique depart from respectively surface of the work, carries out reset instruction.
In the above-described embodiments, need select the digital control system 840d with binary channels function, will control the first passage that left bistrique is upper and lower, 2 axis servomotor X1 axles, Z1 axles that move left and right are assigned to control system; The second channel that right bistrique is upper and lower, 2 axis servomotor X2 axles, Z2 axles that move left and right are assigned to control system will be controlled.
In the specific implementation, can use NC procedure piece and PLC program block, wherein:
(1) NC procedure piece can comprise following program:
1. circle end face combines grinding main program: %_N_NEIKONG_DUANMIAN_MPF;
2. cylindricalo grinding subprogram: %_N_L13_SPF;
3. left bistrique reset subprogram: %_N_L1_SPF;
4. cross grinding main program: %_N_DUANMIAN_MPF;
5. cross grinding subprogram: %_N_L23_SPF;
6. right bistrique reset subprogram: %_N_L1001_SPF;
(2) PLC program block can be realized following functions:
1. axle enables, passage is controlled, anxious stop and extremely interrupt, interruption reset condition: OB1;
2. miscellaneous function: FC100.
While adopting above-mentioned NC procedure piece and PLC program block, the method for grinding of the numerical control compound grinding machine of above-described embodiment can be:
Step 1: call circle end face combination procedure (%_N_NEIKONG_DUANMIAN_MPF) in first passage;
Step 2: operation circle end face combines procedure (%_N_NEIKONG_DUANMIAN_MPF) automatically in first passage;
Step 3: channel selecting and the anti-misinterpretation of routine call relation
Because of structure and the axis servomotor symmetrical distribution form of numerical control compound grinding machine, the necessary corresponding left bistrique program of first passage and combination procedure, the necessary corresponding right bistrique program of second channel; If call error, two passages of independent operating can lose mutually and link up and coordinate by wrong selection working procedure separately, produce unexpected consequence; So whether, after combination grinding program (belonging to first passage) operation, is first passage by procedure judges current channel state, further whether the operation of verification step 1 and step 2 is correct;
If accidentally selected left bistrique program or combinator at second channel, program can exit automatically, will not start.Program also could automatically exit and will not start, and points out channel selecting mistake if selected right bistrique program at first passage on the contrary! Must reselect passage and program could move;
Step 4: binary channels interruption reset condition (Real-Time Monitoring)
In grinding process, there will be unavoidably abnormal conditions, now need each shifting axle in binary channels to leave fast finished surface, get back to initial position; Generally be divided into following several situation: 1. artificial request is interrupted and resets, and 2. auxiliary movement is abnormal, 3. left and right mill frame anti-collision warning;
Above several status signals are input to PLC input, through the processing of PLC interruption reset condition program, abnormal conditions are exported to NC fast, NC program receives after quick-speed interruption signal, interrupts the current program segment moving at once, automatically enters reset routine
Step 5: the right bistrique procedure (%_N_DUANMIAN_MPF (%_N_L23_SPF) that calls second channel
It is in service that today's numerical control system is in first passage, make right bistrique in second channel also automatically move the cross grinding program %_N_DUANMIAN_MPF of appointment, must coordinate instruction INIT (2 by the specific passage of digital control system, " DUANMIAN ", " n "), in second channel, call cross grinding program
Step 6: the right bistrique procedure (%_N_DUANMIAN_MPF (%_N_L23_SPF) of operation second channel
Step 5 completes the appointment of second channel program name, but program also can not move, and needs an instruction enable second channel operation, and in this case, NC program adopts M code to connect PLC, then with PLC instruction, second channel is moved automatically.Finally allow right bistrique also according to set cross grinding program, automatically move.
Step 6.1-6.2: right bistrique is by normal grinding process flow process grinding end face, until cross grinding finishes, if now also undressed end of left bistrique of the automatic end of output sign M30. of NC program, left bistrique continues grinding, be not subject to the impact of right bistrique, until Excircle machining finishes.After Excircle machining finishes, now the passage in first passage is coordinated instruction meeting and is retrieved right bistrique grinding and finish to identify M30, because right bistrique finishes grinding prior to left bistrique, therefore first passage is confirming also to stop the operation of self after second channel finishes.If the first grinding of left bistrique cylindrical is complete, first passage can wait for that second channel grinding finishes after sign appearance, then finishes self-operating.
Step 7: call and move left bistrique procedure (%_N_L13_SPF)
Deng coordinating two interchannel operational relations, first passage also starts to call and move cylindricalo grinding subprogram-%_N_L13_SPF, completes left bistrique cylindricalo grinding;
Step 7.1-7.2: left bistrique is by normal grinding process flow process grinding cylindrical, until cylindricalo grinding finishes, after Excircle machining finishes, now the passage in first passage is coordinated instruction meeting and is retrieved right bistrique grinding and finish to identify M30, until second channel grinding finishes after sign appearance, finish self-operating, combination grinding finishes again.
Compared with prior art, the method for grinding of the numerical control compound grinding machine of above-described embodiment, the performance advantage that can reach, can be referring to table one.
Table one: the performance table of comparisons of above-described embodiment and prior art
