standard drawing for engineering

1.    Standard Drafting
Standard technical drawing is a uniformity that has been agreed in order to avoid misunderstandings in communication techniques. People involved in the field of engineering drawings need to know about the standards. Related persons include students in technology and industry groups, the product planners, machine operators, assembly operators, mechanics and control the quality of a product / machine.
 Standard drawing techniques can be applied within the company, between companies / industries within a country, even the standard can be applied to engineering drawings of industrial inter-state known as International Standards or abbreviated SI. Countries that have made a standard is:
a.    Japanese Industrial Standard (JIS)
     for more info: JISC
b.    Nederland Normalisatie Instituut (NNI)
     for more info: NNI
c.    Deutsche Industrie Normen (DIN)
                      for more info: DIN
d.    Standar Nasional Indonesia (SNI)
     for more info: SNI
e.    American National Standard Institute (ANSI)
     for more info: ANSI
f.     International Organization for Standardization (ISO)
     for more info: ISO
ISO (International Standardization for organization) aims to bring together the technical understanding between nations by making a standard. The standards that were then brought to an international forum with the aim for:
a.    Facilitate national and international trade
b.    Facilitate communication techniques
c.    For developing countries, it can give handy hints on specific issues  in the field of engineering.

2.    Drafting Pencils
The tools used to describe the scratch line in the image. Pencil is divided into two kinds of pencils, which is:
1)    based on the shape:
                    a.   Pencil rod, whose contents fused with rods.
                    b.  Mechanical pencils, pencil that can be reloadable.
2)    Based Hardness. These pencils have different hardness levels and usually denoted by the letter (F = Firm, H = Hard, B = Black). Here is link to more details Story of pencil

3.    Technical Pen is a drawing tool for drawing ink on tracing paper, and has a thickness  levels. This tool requires regular maintenance that can still be used as it should be. for more detail please visit Technical_pen


4.    Compass (drawing tool) is a drawing tool that is used to create a circle by plugging one end of the rod on a paper image as a center of the circle and the other serves as a pencil to draw a line.The following link for more details Compass



5.    Drafting Board must have a flat surface, straight and smooth. Adequate size drawing board for engineering drawings is 1265 mm long, 915 wide and 30mm thick. complete the following link drafting board


6.    Protractor used to divide an angle into equal size. Generally made of mica and come  with dividers ranging from 0°-360°. Complete the following linkProtractor



7.    Paper which is used to create engineering drawings are white drawing paper whose surface is not rough. If the rough drawing paper will be difficult to draw a straight line with ink.
Type of drawing paper commonly used in engineering drawings comprise three types, namely:
a.    Paper millimeter blocks, namely a thick white drawing paper that has a horizontal line and a vertical line with a distance of 10 x 10mm. Chart paper serves to create temporary images generated from the measurement results with the scale.
b.    Thick white paper, which is paper ordinary image that is often used to create images with the scale and the actual size (A0, A1, A2, A3, etc.). Link below for the full sizePaper_size
c.    Tracing paper, transparent paper that is used to create an image with ink. following a full description\Tracing_paper

8.    triangle ruler consists of one angle of 45 °, 90 °, 45 ° or an angle of 30 °, 90 ° and 60 °. A pair of triangle ruler is used to create parallel lines, special angles and lines perpendicular to each other. for more details ruler  steel square

9.    Eraser is used to erase pencil lines that are not useful in order not to damage the paper drawing and does not leave colour on paper drawing of fine white eraser use. for eraser

1.     Standar Gambar Teknik Standar gambar teknik merupakan suatu keseragaman yang telah disepakati bersama dengan tujuan untuk menghindari salah pengertian dalam komonikasi teknik. Orang-orang terkait dalam bidang gambar teknik perlu mengetahui tentang standar. Orang-orang terkait tersebut antara lain siswa pada kelompok teknologi dan industri, para perencana produk, operator mesin, operator perakitan, mekanik dan pengontrol mutu dari suatu produk/mesin. Standar gambar teknik dapat diberlakukan di dalam lingkungan perusahaan, antar perusahaan/industri di dalam suatu negara, bahkan standar gmbar teknik dapat diberlakukan pada industri antar negara yang dikenal dengan Standar Internasional atau disingkat SI. Negara-negara yang sudah membuat standar antara lain : a.     Japanese Industrial Standart (JIS)      Lebih lengkapnya : JISC b.     Nederland Normalisatie Instituut (NNI)    ...

Wanna Know Engine Ignition? Read this Function and Development of Ignition System First

Image
A.Ignition system       An engine can generate power due to the combustion occurs in the engine. Powered engine combustion heat is converted into mechanical energy, called engine fuel.      There are some kind of engine fuel, which is the gasoline engine. In the gasoline engine thermal energy obtained by burning a mixture of fuel and air in the cylinder. The combustion process in gasoline engine starts the spark jumps.      Engine gasoline, gas into the cylinder is a mixture of air and fuel, the mixture is then burnt to produce combustion pressure later converted into mechanical power.      The system used is an electric ignition system, which is used to generate sparks electrical voltage as a sprinkler. Because the gasoline engine combustion process initiated by a high voltage sparks produced by spark plugs, several methods necessary to produce the required high voltage current.      The ignit...

Jangan Ngaku Anak SMK kalau belum tau sistem pengapian

Image
A.          Sistem Pengapian Suatu mesin dapat menghasilkan tenaga disebabkan didalam mesin tersebut terjadi pembakaran. Mesin bertenaga panas menghasilkan pembakaran yang dirubah menjadi tenaga mekanik, disebut motor bakar. Motor bakar ada beberapa macam salah satunya adalah motor bensin. Pada motor bensin energi panas diperoleh dari hasil pembakaran campuran bensin dan udara di dalam silinder. Proses pemba k aran pada motor bensin dimulai adanya loncatan bunga api. Pada motor bensin , gas yang masuk ke dalam silinder adalah campuran antara udara dan bensin, campuran ini selanjutnya dibakar untuk menghasilkan tekanan pembakaran yang nantinya dirubah menjadi daya mekanis. Sistem yang digunakan adalah sistem pengapian listrik, dimana untuk menghasilkan percikan api digunakan tegangan listrik sebagai pemercik. Karena pada motor bensin proses pembakaran dimulai oleh loncatan api tegangan tinggi yang dihasilkan oleh busi, beberapa metode dip...
