The deviation threshold that step 103, basis prestore, judges whether the deviate of described X-axis, Y-axis, Z axis, A axle and C axle meets the demands, and by judgment result displays to user.
In the present embodiment, can store deviation threshold corresponding to each axle in advance in the controller, deviation threshold can be arranged according to the specific requirement of workpiece to be processed.Described deviation threshold can at least comprise: X-axis deviation threshold, Y-axis deviation threshold, Z axis deviation threshold, A axle deviation threshold and C axle deviation threshold.

For X-axis, if the deviate measuring the X-axis obtained in step 102 is less than the deviation threshold of the X-axis stored in controller, then the precision of X-axis meets the demands, otherwise does not then meet the demands.For Y-axis, if the deviate measuring the Y-axis obtained in step 102 is less than the deviation threshold of the Y-axis stored in controller, then the precision of Y-axis meets the demands, otherwise does not then meet the demands.The determination methods of other axle is similar.
After determining judged result, can by judgment result displays on a display screen, if the deviate of a certain axle of judgment result displays does not meet the demands, then described user notifies that engineers and technicians solve relevant issues, if the deviate of judgment result displays axle meets the demands, then do not need described user to carry out any operation, follow-up normal work pieces process flow process can be carried out.

Embodiment two
The embodiment of the present invention two provides a kind of numerical control machining center detection method.The present embodiment is on the basis of embodiment one, provides the concrete methods of realizing of the deviate of a kind of detection five axles.In the present embodiment, described driving described Reinshaw probe in step 102 carries out repeated multiple times touching measurement to the calibrated bolck be fixed on described numerical control machining center, obtain the deviate of described numerical control machining center at X-axis, Y-axis, Z axis, A axle and C axle, can specifically comprise following five steps: the deviate of X-axis is measured, the deviate of Y-axis is measured, the deviate of Z axis is measured, the deviate of A axle is measured, the deviate of C axle is measured.
The flow chart of the numerical control machining center detection method that Fig. 3 provides for the embodiment of the present invention two.As shown in Figure 2, the numerical control machining center detection method in the present embodiment, specifically can comprise:
The detection instruction of step 201, reception user input, and control described main axle moving to precalculated position according to described detection instruction, the Reinshaw probe being arranged on described precalculated position is automatically changed to make described main shaft.
Step 101 class in the principle of step 201 and implementation method and embodiment one this, repeat no more herein.
Step 202, the deviate of X-axis to be measured.
Particularly, when measuring the deviate of X-axis, described probe first can be driven to move along X-axis negative direction, when touching described calibrated bolck, stopping driving described probe mobile, and recording the primary importance information at described probe place; Then, described probe is driven to move the first predetermined threshold value along X-axis positive direction; Finally, drive described probe to move along X-axis negative direction, when touching described calibrated bolck, stopping driving described probe mobile, and recording the second place information at described probe place; Described primary importance information and second place information are subtracted each other, obtains the deviate of described X-axis.
In this step, first record probe touches the positional information of calibrated bolck, then allows probe return a segment distance, and again moves along X-axis, then record second time touches the positional information of calibrated bolck.If this position of twice is identical, or the position difference of twice is very little, then can think to there is not deviation in X-axis, otherwise if the position of this twice record is mutually far short of what is expected, then think that X-axis exists deviation, namely the deviate of X-axis does not meet the demands.
Step 203, the deviate of Y-axis to be measured.
Particularly, when measuring the deviate of Y-axis, described probe first can be driven to move along Y-axis negative direction, when touching described calibrated bolck, stopping driving described probe mobile, and recording the 3rd positional information at described probe place; Then, described probe is driven to move the second predetermined threshold value along Y-axis positive direction; Finally, drive described probe to move along Y-axis negative direction, when touching described calibrated bolck, stopping driving described probe mobile, and recording the 4th positional information at described probe place; Described 3rd positional information and the 4th positional information are subtracted each other, obtains the deviate of described Y-axis.
Step 204, the deviate of Z axis to be measured.
The method that the deviate measuring Z axis and the deviate measuring X-axis and Y-axis adopt is similar, specifically can comprise: first drive described probe to move along Z axis negative direction, when touching described calibrated bolck, stopping driving described probe mobile, and recording the 5th positional information at described probe place; Then, described probe is driven to move the 3rd predetermined threshold value along Z axis positive direction; Finally, drive described probe to move along Z axis negative direction, when touching described calibrated bolck, stopping driving described probe mobile, and recording the 6th positional information at described probe place; Described 5th positional information and the 6th positional information are subtracted each other, obtains the deviate of described Z axis.
Step 205, the deviate of A axle to be measured.
Particularly, when measuring the deviate of A axle, first the angle of described A axle can be set to 0 degree, the angle of C axle is set to 0 degree, and drive described probe to move along Y-axis negative direction, when touching described calibrated bolck, stop driving described probe mobile, and record the 7th positional information at described probe place; Then, described probe is driven to move the 4th predetermined threshold value along Y-axis positive direction; Finally, the angle of described A axle is set to 0 degree, the angle of C axle is set to 180 degree, and drives described probe to move along Y-axis negative direction, when touching described calibrated bolck, stopping driving the movement of described probe, and recording the 8 positions information at described probe place; Described 7th positional information and 8 positions information are subtracted each other, obtains the deviate of described A axle.
In this step, first touch calibrated bolck and record position information when 0 degree, A axle, 0 degree, C axle, then, again touch calibrated bolck and record position information when 0 degree, A axle, 180 degree, C axle.If A axle does not have deviation, so no matter C axle is 0 degree or 180 degree, the position that probe touches calibrated bolck should be all identical, if A axle exists deviation, so after C axle goes to 180 degree from 0 degree, the distance between probe and calibrated bolck can change, cause the positional information of twice record difference or fall far short, so the positional information before and after rotating according to C axle, just can know whether A axle exists deviation.
Step 206, the deviate of C axle to be measured.
Particularly, when measuring the deviate of C axle, first the angle of described A axle can be set to 90 degree, the angle of C axle is set to 0 degree, and drive described probe to move along X-axis negative direction, when touching described calibrated bolck, stop driving described probe mobile, and record the 9th positional information at described probe place; Then, described probe is driven to move the 5th predetermined threshold value along X-axis positive direction; Finally, the angle of described A axle is set to-90 degree, the angle of C axle is set to 0 degree, and drive described probe to move along X-axis negative direction, when touching described calibrated bolck, stopping driving the movement of described probe, and recording the X position information at described probe place; Described 9th positional information and X position information are subtracted each other, obtains the deviate of described C axle.
In this step, first touch calibrated bolck and record position information when 90 degree, A axle, 0 degree, C axle, then, when A axle bear 90 degree, 0 degree, C axle again touch calibrated bolck and record position information.If C axle does not have deviation, so no matter A axle is 90 degree or negative 90 degree, the position that probe touches calibrated bolck should be all identical, if C axle exists deviation, so after A axle goes to negative 90 degree from 90 degree, the distance between probe and calibrated bolck can change, cause the positional information of twice record difference or fall far short, so the positional information before and after rotating according to A axle, just can know whether C axle exists deviation.
The deviation threshold that step 207, basis prestore, judges whether the deviate of described X-axis, Y-axis, Z axis, A axle and C axle meets the demands, and by judgment result displays to user.
Principle and the implementation method of the step 103 in step 207 and embodiment one are similar, repeat no more herein.
In the numerical control machining center detection method provided in the present embodiment, give the concrete methods of realizing of the deviate of detection five axle, by measuring the deviate of X-axis, measuring the deviate of Y-axis, measure the deviate of Z axis, measure the deviate of A axle and measure the deviate of C axle, the measurement to five axle precision can be realized easily and quickly.
On the basis of the technical scheme provided at above-described embodiment, preferably, carry out repeated multiple times touching measurement to the calibrated bolck be fixed on described numerical control machining center at described driving described Reinshaw probe, obtain described numerical control machining center after the deviate of X-axis, Y-axis, Z axis, A axle and C axle, can also measure relative to the deviate and the postrotational deviate of C axle of waving direction the postrotational deviate of A axle, A axle, and judge whether above-mentioned three deviates meet the demands.
The postrotational deviate of A axle is measured and is judged, specifically can comprise:
The angle of described A axle is set to the first predetermined angle, and drives described probe to move along Y-axis negative direction, when touching described calibrated bolck, stopping driving described probe mobile, and recording the 11 positional information at described probe place;

Described 11 positional information and the 12 positional information are subtracted each other, obtains the postrotational deviate of described A axle;
By the postrotational deviate of described A axle compared with the postrotational deviation threshold of A axle prestored, and judge whether the postrotational deviate of described A axle meets the demands.
Wherein, described first predetermined angle specifically can be arranged according to actual conditions, in the present embodiment, described first predetermined angle can be 10 degree, A axle can be measured like this along the deviate after positive direction rotation 10 degree, by this deviate compared with the postrotational deviation threshold of A axle prestored, the deviation threshold prestored if be less than, just can judge that the postrotational deviate of A axle meets the demands; Or described first predetermined angle can be-10 degree, A axle can be measured like this and rotate the deviate after 10 degree along negative direction, and whether A axle is met the demands along the deviate after negative direction rotation 10 degree judge.
Further, A axle can also be rotated the deviate of 10 degree along positive direction and A axle subtracts each other along the deviate of negative direction rotation 10 degree, and using the value after subtracting each other as the postrotational deviate of described A axle, and compared with the postrotational deviation threshold of A axle prestored, judge whether to meet the demands.
