Rationale Of Mechanical Engineering Graphics

Mechanical engineering graphics is specific means of communication with the help of size, shape, general and specific features and physical objects. Mechanical engineering graphics is referred as universal idiom of engineering.

Standards of mechanical engineering graphics:

Similar to writing language or verbal communication has its own standards; technical drawing or mechanical engineering graphics has a standard called ANSI Y14.5. ANSI Y14.5 is also referred as ISO standard. This standard can be easily understood with the knowledge of engineering drawing.

Basics of mechanical engineering graphics:

Mechanical engineering graphics includes the following.

• Projected views: Object side views are projected as required.
• Cross sections: Cross sections represents interior feature.
• Table: Table is placed at right end corner. It includes the representation of part name, name of the designer, and information related to object.
• Dimensions: The top most complicated part of representation.
• Tolerance: Each and every technical drawing has critical dimension called tolerance. Tolerance of engineering graphics is of two type’s namely dimensional tolerance and geometric tolerance. In general geometric tolerance represents shape of object. For instance straightness, circular, flat, cylinder, angular, perpendicular, parallel and concentric.
• Standard fits: Standard fits represent fit in between shaft and hole. For instance locational, running, force, shrinks and transition clearance fit are types of standard fits.
