Description
Technical field
The present invention relates to field of machining, be specifically related to a kind of workpiece surface quality case study trial cut device and analysis method.
Background technology
Surface quality is to evaluate an important indicator of workpiece quality, machine coordinates shaft vibration in processing can cause that workpiece produces surface quality problems, when machine tooling complex part, because multiple coordinate axess simultaneously participate in processing, surface quality problems Producing reason can be made to become more complicated.At present the judgement of this problem mainly there are two kinds of methods, one is based on experience, formulate sequencing, each coordinate axes is overhauled, the order of accuarcy of this method is according to the experience of machine upkeep personnel, and often occur positioning the inaccurate a large amount of useless work caused, even can therefore destroy original mechanical performance, cause lathe prolonged shutdowns.Two is, by circularity test, each coordinate axes is carried out dynamic property detection, and this method is higher to machine upkeep personnel requirement, and cannot provide and analyze result qualitatively.
Summary of the invention
It is an object of the invention to, the reason existed for solving prior art positions inaccurate, the problem of long processing period, the invention provides a kind of workpiece surface quality case study trial cut device and analysis method, separately machined by each coordinate axes, complicated multiaxis is processed simultaneously the workpiece surface quality PROBLEM DECOMPOSITION of generation, it is achieved failure cause accurate, quickly position.
To achieve these goals, the technical solution used in the present invention is:
A kind of workpiece surface quality case study trial cut device, including base, described base is rectangle, and base is provided with X-axis test specimen, Y-axis test specimen, Z axis test specimen, A axle test specimen, B axle-C axle test specimen and initial point hole；Described X-axis test specimen, Y-axis test specimen and A axle test specimen are strip projection, and all with the sides aligned parallel of base；Described X-axis test specimen is arranged at the edge of base, Y-axis test specimen and A axle test specimen and is respectively arranged at the edge of the base adjacent with X-axis test specimen；Described Z axis test specimen is longitudinal section is trapezoidal projection, and is arranged at the middle part of base；Described initial point hole is blind hole, is arranged at the middle part of Z axis test specimen top planes；Described B axle-C axle test specimen is circular, is arranged between Z axis test specimen and X-axis test specimen, Y-axis test specimen and A axle test specimen.

One, minimum axle is adopted to participate in the principle of processing during trial cut；
Two, each trial cut axle is forward and reverse processes respectively；
Three, the workpiece minimum thickness of each trial cut axle must not lower than 8MM；
Four, the position gone wrong when Multi-axis Machining carries out the separately machined of each coordinate axes；
Five, the parameters such as the original system data of lathe, offset data are used；
Six, the parameters such as the original feed speed of technique, the speed of mainshaft are used；
Seven, the parameters such as the original sword number of cutter, the number of teeth are used；
Eight, it is not involved in the coordinate axes of processing, adds and clamping function when having clamping function man-hour, should be used.
Surface quality problems analytical procedure:
One, which coordinate axes employing lathe is found in program.
If processor is as follows:
X0Y0Z0A0C0
X1Y1Z1A1C1
X2Y2Z2A2C2
Above processor employs X, Y, Z, A, the C axle of lathe.
In the position that workpiece goes wrong, trial cut device is installed.
Two, the position that workpiece is installed on lathe:
X100Y100
Above coordinate is the coordinate position that workpiece is arranged on lathe, and trial cut device also needs to be arranged on the position of X100Y100.
By each coordinate axes trial cut on the position gone wrong participating in processing.
When analyzing X-axis, A axle test specimen 4 clamps, and X-axis test specimen 1 is along positive and negative directionally independent processing, there is machined parameters during surface quality problems in machined parameters selection workpiece, and such as 20000 revs/min of main shaft, feed speed 7000mm/ divides, axial every layer of cutting 3MM, radially every layer of cutting 3MM, thickness of workpiece 8MM；
When analyzing Y-axis, A axle test specimen 4 clamps, and Y-axis test specimen 2 is along positive and negative directionally independent processing；
When analyzing Z axis, A axle test specimen 4 clamps, and for avoiding Y-axis or Z axis to have additional equilibrium device to affect the separately machined effect of Z axis test specimen 3, therefore this axle is combined and do not had the X-axis test specimen 1 of additional equilibrium device to carry out oblique surface machining；
When analyzing A axle, A axle test specimen 4 is along positive and negative directionally independent processing；
When analyzing B axle, A axle test specimen 4 clamps, and B axle test specimen is along positive and negative directionally independent processing；
When analyzing C axle, A axle test specimen 4 clamps, and C axle test specimen is along positive and negative directionally independent processing.
The each ingredient of test specimen illustrates:

Z axis test specimen 3, is placed on test specimen central authorities along X-axis.The inclined surface in left side is for detecting the Vibration Condition of Z axis positive movement, and the inclined surface on right side is for detecting the Vibration Condition of Z axis negative movement.Angle of inclination is variable；
A axle test specimen 4, is placed on the right side of test specimen along Y-axis.The surface in left side is for detecting the Vibration Condition of A axle positive movement, and the surface on right side is for detecting the Vibration Condition of A axle negative movement；
B axle test specimen, is placed on test specimen central authorities along Z axis.The inclined surface of inner side is for detecting the Vibration Condition of B axle negative movement, and the inclined surface in outside is for detecting the Vibration Condition of B axle positive movement.Angle of inclination is variable；
C axle test specimen；It is placed on test specimen central authorities along Z axis.The inclined surface of inner side is for detecting the Vibration Condition of C axle positive movement, and the inclined surface in outside is for detecting the Vibration Condition of C axle negative movement.Angle of inclination is variable.
Embodiment described above only have expressed the detailed description of the invention of the application, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the application protection domain.It should be pointed out that, for the person of ordinary skill of the art, under the premise conceived without departing from technical scheme, it is also possible to make some deformation and improvement, these broadly fall into the protection domain of the application.
