Technical Drawing Standardization Function and Explanation

Rancakmedia.com – The following is an explanation of the image standardization function that image lovers may not know about. So, let's read the article below carefully and carefully.

Standard technical drawings, which generally appear more in the form of letters and numbers. Usually, letters and numbers serve to explain visuals.

To complete the information on technical drawings so that there are no misunderstandings, letters, numbers and symbols must be arranged convincingly with additional information or explanations.

Then, enter letters and numbers on the line so that they comply with standards. In engineering drawing, many types of lines are used, each with its own meaning and use.

Engineering Drawing Activities

In a location known as a drawing studio, technical drawing tasks are carried out (engineering design department). Engineers who are responsible for creating design drawings are known as designers.

Understanding Technical Drawing

Engineering drawings is a tool used by technical specialists to communicate your thoughts and concepts, which can also be called technical language. As a language, technical drawings must convey information well and objectively.

Technical Drawing Functions

Technical drawings serve three purposes: transmission of information, documentation, and expression of development concepts.

Submit information

In the early days of industry, the same individuals were responsible for the planning and production of technical products. There is no need for guidelines in this case because the image only functions as a depiction of an idea.

Once the industry began to develop, separate individuals were responsible for the planning and production of technical products. In this case, drawings serve as a way for designers (drafters) and manufacturers (operators) to share information.

Documentation Materials

Technical drawings are important documents that offer brief technical information about a product. By saving and archiving images for use as information, the images are documented.

Generating Ideas for Development

In drawing form, the designer draws from an abstract conception of technical materials into form (usually a sketch). The image is then continuously viewed and studied so that the perfect image can be created.

Understanding Image Standardization

Image standardization involves standardizing how images are created and interpreted. If people in an engineering environment who create and read engineering drawings use the same standards, this means the engineering drawings are standardized.

Image Standardization Function

The following is the function of standardizing technical drawings:

  1. To provide clarity to image creators and readers regarding the suitability of image guidelines.
  2. A uniform interpretation of the use of symbols is displayed visually.
  3. This facilitates communication between artists and image consumers.
  4. Facilitate business cooperation in mass production of technical goods (mass production).
  5. Streamlining production and distribution of spare parts.

Types of Standardization

Among the most prominent standards are:

  1. JIS (Japanese Industrial Standard), industrial standards in Japan.
  2. NNI (Nederland Normalisatie Instituut), industrial standardization in the Netherlands.
  3. DIN (Deutsche Industrie Normen), industrial standardization in Germany.
  4. ANSI (American National Standards Institute), industrial standards in America.

In addition, our country has national standards. previously known as Indonesian Industrial Standards (SII).

However, after the issuance of Government Regulation Number 15 of 1991 concerning Indonesian National Standards, it was replaced with the Indonesian National Standard (SNI). The National Standardization Council manages SNI (DSN).

ISO International Standard

To meet world demands, the International Organization for Standardization (ISO) was established as an international standards-setting body (ISO).

The International Organization for Standardization (ISO) was formed on October 14 1946 as a replacement for the International National Standardizing Association (ISA) which was dissolved in 1942.

By setting standards, ISO aims to harmonize technical knowledge between countries. ISO/TC 10 is the name for the engineering drawing standards committee. The National Standardization Council represents Indonesia's membership in ISO. Indonesia is a member of ISO.

Image Properties and Development of Image Standards

The following is an explanation of image properties and the development of image standards, including:

Image Certainty

The role of images as a source of information, connecting designers with the people who use them, should offer definitive information and should not give rise to uncertainty.

Due to the variety of products, it is difficult for experienced employees to differentiate the importance of individual photos. In a language, symbols must replace tones, and meaning must be universally standardized.

When creating standards, it is important to think about how much certainty can be created, because the best conditions for the standards need to be created.

Relationship between Function and Image Properties

Information transmission is the most important function of an image, which is controlled by several aspects. Therefore, the way information is disseminated must be prioritized above others.

Simplification of drawings and reduced drawing ability can result in drawing defects. In other words, an image that others will use must be created and similar information must be passed on.

The Nature and Development of Image Standards

As previously indicated, drawing standards combine information preparation and information delivery, and as previously indicated, clarity plays a role.

In developing drawing standards, it is very important to determine the ideal state of the current state of technology and to choose between these contradictory criteria.

ISO/TC10 Framework and Field of Work (Technical Drawings)

The following is the framework and areas of technical drawing work, including:

ISO/TC 10 Framework

Engineering drawings have played an important role in the standardization of engineering drawings to provide engineering drawings with a global character as an international technical language.

Under SC1, which sets the overall regulatory standards for engineering drawings, there are two main categories: emblem drawings and working drawings.

According to the various fields, the symbol image part is further separated into SC2, SC3, and SC4. SC5 manages three SCs that manage various specialized sectors, such as equipment, steel frames and buildings.

SC5 is in charge of dividing the job drawings, which means determining sizes and tolerances.

ISO/TC Activities 10

The following are the activities of IDO/TC 10, including:

SC Activity 1 (Basic Principles)

SC 1 has set broad standards for drawing and is responsible for most of the assignments of TC 10. The most significant assignment of SC 1 is learning to present the basics.

The findings have been specified in ISO/DIS 128, which includes the presentation of steel frames and building drawings following the establishment of the 128 ISO/R 1958 recommendations, which are currently being reviewed and improved.

Live image presentation is a method of displaying something using a single image display. For letters, ISO 3098/Z has developed a set of numbers and letters that are specifically printed using letter screen printing.

A scale has been used to classify preferred prices. The surface configuration of a component can be shown in a drawing using symbols to indicate surface roughness and machining direction.

The symbols for welds in the drawings have been determined by the depiction of the symbols in the drawings.

Provides Tolerances and Sizes

SC 5 has dealt with size and tolerance issues and has the following responsibilities:

  1. Size and tolerability must be determined.
  2. Tolerance and standing (geometric tolerance).
  3. You provide specific sizes and tolerances for elements.
  4. Dimensions and tolerances.

The standard specifies how image sizes are allocated, and the standard is currently under review and revision. The main causes of repair are:

  1. Size adjusters for the structure must be provided.
  2. As far as possible, symbols should be used for internationalization rather than notes in one language.
  3. ISO/R 406 specifies the representation of linear and angular tolerances.
  4. Display of drawing tolerances for shape, position, location, and rotational deviation (out).

Geometric tolerance is a description of the tolerance of shape, position, location and rotational deviation. The acceptable range for an element (such as a point, axis line, surface, etc.) is determined by its geometric tolerance.

  1. Provides Specific Element Sizes and Tolerances.
  2. When it comes to unique parts like cones, the way sizes and tolerances are given should be clear and the same everywhere.
  3. SC 6 Operations (Special Presentation of Technical Drawings).
  4. Special presentations are managed in SC 6 and categorized as.
  5. Conventional or efficient depiction of machine components or machine parts.
  6. Presentations in specialized domains like glassware, optical components, and pipelines, etc.
  7. Process labeling on images.

SC 2, SC 3 and SC 4 activities

Vacuum technology symbols are the main concern of SC 2. Instrument symbols have been provided in SC 3. SC 4 defines kinematic symbols, which are used in machine frame diagrams to show how machine parts work in terms of kinematics.

Duties of Designers, Draftsmen and Image Users

A designer's work begins with creating a drawing. The preliminary drawing is then studied to identify what material the component should be made of and how it should be made.

The designer must also provide information about the number of parts to be produced and their assembly. Using the results of the analysis, the sketch is converted into a design drawing that provides specific information. As a consequence of the design process, working drawings are the final product.

A designer is supported in creating working drawings by a draftsman who is responsible for presenting the information on the drawing concisely while incorporating all of the designer's ideas.

When providing a drawing description, a draftsman should always check with the designer or process planner.

The operator is responsible for converting the image into a physical object. Apart from being able to operate the machine, an operator must be able to read drawings or know how to draw according to drawing standards.

Conclusion

So that is the definition of the function of standardizing technical drawings. In engineering drawing, many types of lines are used, each with its own meaning and use. Letters and numbers function to explain visuals.
