The submethod that skill specification and each specification are applicable is encoded, and auxiliary code defines in design information and is heat-treated particular/special requirement to part,
It is heat-treated for auxiliary judgment peculiar part；Surface treatment requires that every section of Coded is six, respectively 4-digit number and two
Alphanumeric, preceding 4-digit number represent process of surface treatment specification, and first alphanumeric is represented in technological specification
Applicable submethod, last alphanumeric represent overburden cover or japanning color type；Special examined requirement point
Two are encoded to, is two digits；The each one-level feature of geometric properties Coded is using a letter expression, each secondary characteristics
And option is represented using one-bit digital；Woollen size Coded is represented using a letter.Auxiliary code is reserved place, for letter
Being combined with numeral, auxiliary code includes key characteristic Coded, if auxiliary code need to be assigned its content to primary key complementary definition,
This yard of section can be default, does not influence part classification；Workpiece's decomposition and rew is the linear superposition of each Coded, configures workpiece's decomposition and rew
Before, the structure of pre-configured each Coded, then each Coded is quoted in workpiece's decomposition and rew structure.
Second level part manufacturing process coding is on the basis of first order workpiece's decomposition and rew, with process planning, work
The processes such as skill planning and designing gradually form, and improve and issue, and are easy to establish between workpiece's decomposition and rew and work flow coding
Logical relation, while technique detailed design can be supported, ERP decision-makings, operation are supported, for production line simulation and balance etc..Such as Fig. 4
Shown, part manufacturing process coding in the second level includes process Coded, Technology for Heating Processing Coded, process of surface treatment point
Coding and special examined technique Coded, it is different from first order workpiece's decomposition and rew mode, from the aspect of four dimensions, division
For four code sections.Each code section is perfect according to first order workpiece's decomposition and rew supplement, and process Coded is by two (one digit numbers
Word and a letter) sequentially form total code bit for one group, for different part classes, the total code bit of process is indefinite, i.e. technique side
Method is variable code, and in order to be connected with first order workpiece's decomposition and rew, process Coded form is made up of " primary key+auxiliary code ",
Basic code is structure name Coded and part type Coded in first order workpiece's decomposition and rew wherein in primary key, and variable code is work
Process major class is encoded with subclass, and auxiliary code is reserved place, and follow-up definable part machining cell coding or numerically controlled processing equipment are compiled
Code；Technology for Heating Processing Coded is one-bit digital；Process of surface treatment Coded is one-bit digital；Special examined technique Coded
For two digits.
Third level part manufacturing recourses coding primary key is substantially basically identical with second level part manufacturing process coding, when same
When class part has multiple Standard processing protocols, system is identified by auxiliary code, as shown in figure 5, part manufacturing recourses are compiled
Code front two represents production and processing unit (pressing subsidiary factory of enterprise coding+workshop section's code), and center section represents typical process name,
Perfect, rear two expressions operation requirement is refined on process basis of classification in the part manufacturing process coding structure of the second level
(typical operation example, typical operation program etc.).
Preferably, third level part manufacturing recourses coding is expressed on product parts in a manner of Quick Response Code.
