Detailed description of the invention
Fig. 1 is the process step of the invention figure.
Specific embodiment
Below by specific embodiment, the invention will be further described, and it is not limit that following embodiment, which is descriptive,
Qualitatively, this does not limit the scope of protection of the present invention.
A kind of analysis method for reliability for mechanical processing technique, this method is using Deviation Analysis Method to machining
The FMECA method of technique is supplemented, and specific step is as follows for this method:
Step 1: according to method as defined in GJB/Z 1391-2006 carry out system definition, technology trouble pattern analysis and
The technology trouble analysis of causes.
Step 2: partitioning site, node refer to the component part for the system studied, and are to have to determine boundary
Equipment (pipeline between such as two containers) unit；
The division of node will follow following principle: a until design idea next change, design idea be system operation and
The potential objective law of its component part；Great change of the b up to process conditions；C is until next equipment.
Step 3: each ready-portioned node being analyzed, deviation is generated, then the event of technique caused by analysis deviation
Barrier mode；
The method that deviation generates is as follows:
Firstly, determine introducer to be used and the technological parameter to be analyzed of each node, introducer be for stating and
Define the word or phrase of element/characteristic parameter specific type deviation；
Table 1 is common introducer and its meaning, common technological parameter include: flow, temperature, pressure, liquid level, the time,
PH value, frequency, voltage, mixing, separation, composition, speed, viscosity, signal, additive, reaction etc..
Table 1 often uses introducer and its meaning
| Introducer | Meaning |
| Without/do not have | To the negative of design idea |
| It is more | Quantity increases |
| It is less | Quantity is reduced |
| And/adjoint | Undesirable movement or output has occurred while complete design is intended to |
| Part | Only complete a part of design idea |
| On the contrary | Design idea opposes in logic |
| Before/after | It is related with the sequence of order |
| Early late | Different from the selection of time of design idea |
| It is too fast/excessively slow | The time that step is completed is more or few than predetermined required time |
Secondly, generating deviation, deviation is that process operation deviates normal operating condition, is typically in the form of " introducer+technique ginseng
Number " selects a technological parameter to ready-portioned a certain node, and one introducer of reselection analyzes the technique event that may cause
Barrier mode continues next technological parameter after having analyzed all significant introducers, has analyzed a node, then carry out
The analysis of next node, until having analyzed.
Step 4: all obtained technology trouble modes being merged into the same FMECA table, according to GJB/Z1391-
Method as defined in 2006 carries out technology trouble impact analysis and HAZAN.The technology trouble mode caused by deviation, work
Skill failure cause is the deviation.
Specific example: applied in Vehicle Processing technique turning and hole
Below with reference to the turning and the specific case study on implementation of hole work step being applied in Vehicle Processing technique, for machining
Technique own characteristic carries out detailed analysis using the improved FMECA method of variance analysis.
The present invention analyzes the FMECA method of turning and hole work step application enhancements in Vehicle Processing technique:
Step 1: the regulation according to GJB/Z 1391-2006 " fault mode, influence and HAZAN guide " is
The function in system definition, turning and hole is processing excircles or hole, process are as follows: installation lathe tool → installation workpiece → Vehicle Processing.
Carry out technology trouble pattern analysis, the technology trouble mode analyzed has: cylindricity is overproof, circularity over tolerance, end
Face verticality and flatness are overproof, repeat spacing ripple, regular ripple, the ripple that causes confusion, surface roughness occur
It is overproof.
Analysis process fault mode reason, can obtain that the results are shown in Table 2:
The 2 technology trouble analysis of causes of table
Step 2: the function in partitioning site, turning and hole is processing excircles or hole, process are as follows: installation lathe tool → peace
Fill workpiece → Vehicle Processing.Therefore, three nodes are divided into, i.e. installation lathe tool, installation workpiece, vehicle.
Step 3: generating deviation.
Firstly, introducer needed for determining are as follows: higher, relatively low, excessive, too small, not parallel, too fast.
The technological parameter of lathe tool: lathe tool position is installed；The technological parameter of workpiece: the location of workpiece, workpiece axle center and vehicle is installed
Knife direction of travel；The technological parameter of vehicle: the amount of feeding, feed speed
It carries out variance analysis and obtains result as shown in table 3:
3 variance analysis of table
Step 4: the technology trouble mode that two methods are obtained merges, and can obtain that the results are shown in Table 4:
Technology trouble mode and the analysis of causes after the merging of table 4
Technology trouble impact analysis is carried out, the results are shown in Table 5 for analysis:
5 technology trouble impact analysis of table
Density of infection point is carried out according to the regulation of GJB/Z 1391-2006 " fault mode, influence and HAZAN guide "
Analysis, due to the content non-present invention emphasis, therefore result is within the rule out.
Although disclosing the embodiment of the present invention and attached drawing for the purpose of illustration, those skilled in the art can be managed
Solution: do not departing from the present invention and spirit and scope of the appended claims in, various substitutions, changes and modifications be all it is possible,
Therefore, the scope of the present invention is not limited to the embodiment and attached drawing disclosure of that.
