We consider a computer-aided design of technological processes (TP) machining machine parts using computer aided design «Sapr_2010» mixed type.

 

«Sapr_2010» automates appointment planovobrabotki generic surfaces of parts to the calculations and allowances mezhduoperatsionnyh sizes, cutting conditions and standards of the time. Database of materials, machine tools and cutting tool systems provide the design of relevant background information. Formation of the structure of the TS (the sequence of operations and conversions) performed by the user sprimeneniem text editor in the file Text.txt, where there is a working version of the TA. The result of the design is placed vstandartnyh forms Form 3 and 3a, GOST 3.1118-82 "in the file Forma3.txt. Also formed diagrammytrudoemkosti operations automation and labor-intensive processing (by type of machine tools: lathes, milling machines, etc.) used in the TA.

 

«Sapr_2010» allows you to design on-line processes workpieces of arbitrary shape. «Sapr_2010» is also equipped with algorithmic modules, assignment plans (routes) processing model surfaces of machine parts. In this case, algorithmically assigns processing methods, allowances for processing payments mezhduoperatsionnyh size with the appointment requirements of accuracy and surface roughness. For technological transitions are calculated cutting conditions, the main component of the rate of time and energy spent on processing.

 

The main differences «Sapr_2010» from existing sistemyavlyayutsya:

 

1. Using a graphical user interface in the formation of information models of surfaces of parts and technology transitions.

 

2. The presence of algorithmic modules route (plan) treat the most common types of surfaces.

 

3. Settlements between the operating size with the appointment requirements of accuracy and surface roughness to them.

 

4. Exclusive use mathematical models of the cutting.

 

5. The calculation of energy costs for processing.

 

6. Availability of a specialized calculator for raschetovmass parts and blanks.

 

7. Combining design with its TA technical valuation.

 

8. Formation for management diagrammtrudoemkosti operations TA and complexity of types of equipment.

 

 

The presence of algorithmic modules provides the designer the possibility of recommending the appropriate version of the plan (route) processing depending on the final requirements for the dimensional parameters ikachestvennym types of surfaces. Treatment plan is detailed domezhduoperatsionnyh size with the appointment requirements of accuracy and surface roughness to them.

 In appointing the treatment regimes used multifactor mathematical models, oriented to the appointment of the cutting elements (including ipodachi) depending on the values of given parameters and the actual processing conditions.

 

In the design process (TP), the distribution of functions between technology and the computer provides naznacheniestruktury TP (set and sequence of process steps and transitions) directly by the technologist. Tools for Computer Aided Design prietom provide the designer the necessary background information iinitsiiruyut dialog procedure for forming information modeleypoverhnostey parts, components, technology systems and of the process. In the process of dialogue, with использованииспециализированных stylized layout screen, are given details of parts procurement, manufacturing, model surfaces and model tehnologicheskihperehodov.

 

The dialogue process in the appointment process operations, models of machines for them, structures and parameters of the instruments and t.p.obespechivayutsya alternative menus and relevant databases. Priformirovanii information models of surfaces and technological transitions provided the opportunity line editing in the event of random errors.

 

Model calculations: the mass of details and original pieces are provided with a specialized calculator. Mass of billets rolled processing modes and standard time for performing operations and conversions are performed algorithmically.

 The software system consists of basic software (monitor - the core system), the algorithmic modules to assign route processing model surfaces of machine parts, and software modules takzhevzaimozamenyaemyh interactive design major technological transitions, as well as the editing module of the working version of TP imodulya release descriptions of TA holds in standard document. When vypus kestandartnogo document processing operations carried out with determination summarnyhznacheny as the main component of the norms of the time, and most standard time nakazhduyu operation.

 

The modular structure of the system allows to operate the system on IBM-compatible PC with RAM of 900 KB.

 The kernel of the software system are: Monitor the main komandsistemy, database of materials and billets rolled, monitor transactions and databases, the corresponding machines, monitor technological transitions, osnovnogoinstrumenta database, a text editor to edit the working variantatehnologicheskogo process and plug formation process documentation in the standard forms.

 

Algorithmic modules route (plan) treatment of model surfaces (ILO) perform assignments processing methods with the appointment of allowances and payments between the operational dimensions of the requirements for their accuracy to the roughness of the corresponding specialization of the module surface.

 

Methodical provision of uchityvaetispolzovanie in the learning process of engineering specialties university s priosvoenii students aided design.

 

Setoy to use the original software ускоренногопрограммирования among Delphi: software «P_Eskiz_4» and "P_Plan_5x5_13"; modules «ESDP», «SaprTp2000» and «M_Rizba». The tool «P_Eskiz_4» is used for the development of interchangeable software modules формированияинформационных models and types of surfaces technological transitions. Programmnoesredstvo "P_Plan_5x5_13" primenyaetsyadlya approximation table models for the purpose of the cutting elements. Protsedurymoduley «ESDP» and «M_Rizba» vrazrabatyvaemyh fragments used CAD / CAM systems for decomposition of drawing sizes gladkihi threaded surfaces, the definition of tolerance, tolerances, ratings, and the maximum permissible size. Procedures of the module «SaprTp2000» used dlyaopredeleniya details of the material of the workpiece. This technique obucheniyasposobstvuet improvement of knowledge in the disciplines machine-cycle, as well as the development of formal thinking in deepening skills in using computers.
