Specific implementation mode
The invention will be further described in the following with reference to the drawings and specific embodiments.
As shown in Figure 1.
A kind of five-axle linkage machining tool trajectory error method of real-time, maximum feature be trajectory error monitoring for The unrelated acquisition of interpolation cycle-calculating cyclic process, the specific steps are：
First, NC codes, stage extraction and the corresponding theory locus information of sequential storage program segment are read before processing；
Secondly, in process, Servo System of Machine Tools position ring signal processing and analysis, error compensation and homogeneous movement are based on Transformation is learned, the practical cutter spacing point coordinates under workpiece coordinate system is obtained；
Third is determined current real using the method for sequential and practical cutter location-theory locus section relative position relation analysis The corresponding program segment of border cutter location, the space length with corresponding program segment theory locus is trajectory error；Current state rail After the completion of mark error calculation, continue next acquisition-calculating cycle, until process finishing.Such as attached drawing 1, this is the rail of the present invention Mark error method of real-time flow chart reads NC codes and extracts every section of corresponding track letter in effective procedure section before processing Breath；In process, Servo System of Machine Tools position ring acquire home position signal, processing analysis after carry out error compensation and Homogeneous kinematic transform obtains the real-time cutter spacing point coordinates under workpiece coordinate system；Based on sequential and practical cutter location-theory locus Section relative position relation analysis determines theory of correspondences orbit segment, and practical cutter location and the space length of theory locus section are track Error.Continue to recycle next time after completing primary acquisition-calculating cycle, until monitoring terminates.
Such as attached drawing 2, NC codes when source code is the five axis semifinishing of S test specimens extract effective procedure section rail wherein Mark information.The knife rail is made of small straightway, is all made of linear interpolation, so need to only extract every section of beginning and end coordinate .
It is practical cutter location acquisition method schematic diagram such as attached drawing 3.The acquisition of real-time cutter location is broadly divided into three steps：
Step 1: position ring home position signal processing and analysis.For closed-loop digital control system, additional attachment can be passed through Or adapter draws grating scale signal；For semiclosed loop digital control system, code device signal can be drawn.By counting capture card pair Home position signal carries out analysis of accounts, and not compensated machine can be calculated in conjunction with pulse equivalency and initial acquisition position coordinates The original coordinates of kinematic axis under bed coordinate system.
Step 2: analyzing numerically controlled system position controlling unit error compensation mechanism, reading error compensates from digital control system File according to compensation value calculation method offset value calculation therein and compensates original coordinates.With 840Dsl systems of Siemens For system, full closed-loop position control link mainly include measurement system error (Error of leadscrew pitch is corresponded to when semiclosed loop) compensation, Sag error compensation and temperature error compensation, compensation mechanism are as shown in Fig. 4.The wherein benefit of measurement system error and sag error It is piecewise linear interpolation to repay value calculating method, and it is original measurement value that the former, which inputs,；The original measurement of axis on the basis of the input of the latter Value, but export as the error compensation value of compensation axis.Temperature error compensation calculating needs lathe temperature monitoring point temperature value and compensation Axis measured value (compensates) by measurement system error.
Step 3: currently available is the kinematic axis coordinate value under lathe coordinate system, turn error is accounted for it Homogeneous kinematic transform obtains the cutter spacing point coordinates under workpiece coordinate system.The Machine kinematics transformation for mula of different structure form The function and effect of difference, turn error also differ.By taking attached nonopiate 45 ° oblique yaw lathes shown in fig. 5 as an example, consideration is provided The homogeneous kinematic transform formula of turn error.
If L is the design pendulum of B axle away from distance of the knife basic point to rotation axis when that is, B axle rotates；Cutter length is tl；C axis returns It is (X to turn design coordinate value of the center under lathe coordinate systemc0,Yc0)；It is 0 to give tacit consent to B, C axis zero bias, and current zero offset is (X0, Y0,Z0).Changing coordinates are (X, Y, Z, B, C) under lathe coordinate system, and cutter location coordinate is (x, y, z) under workpiece coordinate system.
Wherein, linear axes translation matrix：
Zero offset translation matrix is：
B axle spin matrix is：
C axis rotation matrixes are：
The presence of turn error can influence TBAnd TC.If B axle pendulum is Δ L away from error, B axle eccentricity error is (PBX,PBY, 0), C eccentric shafts are (P away from errorCX,PCY, 0), then consider the B axle and C axis rotation matrixes T of turn errorBEAnd TCEFor：
Use TBEAnd TCESubstitute TBAnd TC.
As shown in Fig. 6, three kinds of relative position relations that practical cutter location is located at theory locus concave side are described.Attached drawing 7 It is shown, list three kinds of relative position relations that practical cutter location is located at the convex side of theory locus.
Such as P in Fig. 6act1IfIt calculatesWithIt corresponds at this time
Such as P in Fig. 6act2IfIt calculatesWithIt corresponds at this time
Such as P in Fig. 6act3IfIt calculatesWithIt corresponds at this time
Such as P in Fig. 7act1IfIt calculatesWithIt corresponds at this time
Such as P in Fig. 7act2IfIt calculatesWithIt corresponds at this time
Such as P in Fig. 7act3IfIt calculatesWithIt corresponds at this time
So PactWith LnAnd Ln+1Position relationship can be divided into 6 kinds of situations, corresponding knAnd kn+14 kinds of codomains combination. Remember that trajectory error vector is
(1)0≤kn≤1&&kn+1When ＜ 0, PactTheory locus correspond to section be Ln,
(2)0≤kn≤1&&0≤kn+1When≤1,
IfThen PactTheory locus correspond to section be Ln,
IfThen PactTheory locus correspond to section be Ln+1,
(3)kn＞ 1＆＆0≤kn+1When≤1, PactTheory locus correspond to section be Ln+1,
(4)kn＞ 1＆＆kn+1When ＜ 0,
IfThen PactTheory locus correspond to section be Ln,
IfThen PactTheory locus correspond to section be Ln+1,
Part that the present invention does not relate to is same as the prior art to be realized using the prior art.
