Learn the common language of Designing, Production, and Quality Engineer, known as Geometric Dimension and tolerancing.
As we know it is impossible to manufacture the exact dimension of the product every time, so we try to manufacture a product within tolerance, this tolerance specifications and technical designing should be well understood by every designing/production/quality engineers.

In design, there is an ideal form of the product with the specification. This specification used to design the product called the work-piece, and the work-piece is a real form of the product, we have to measure it.
As we know it is impossible to manufacture the exact dimension of the product every time, so we try to manufacture a product within tolerance.
A Technical drawing provides us all the technical specifications of the product. Engineering drawing is usually presented in First angle orthographic projection or third angle orthographic projection.
Drawing Symbols The tolerances on the dimensions can be specified in three ways: Unilateral Tolerance System In this system, the tolerance is provided on only one direction from the basic size For example 35.00 plus 0.2,plus 0.5 Bilateral Tolerance system For example 35.00 plus 0.2,Minus 0.5 Limit Dimension system In this system, the size and […]
Tolerance Frame A Tolerance frame also know as feature control frame contains information including Arrow(to represent the area of the technical drawing) Symbol (Hole in below image) Value Shape (Diameter in below image) Datum Symbols Below are the symbols of form, profile, orientation, location, and run-out used in technical drawing. Straightness Type of control: Form […]
A coordinate system is a system that uses one or more numbers, or coordinates, to uniquely determine the position of the points in the space.
Datum A datum is a virtual ideal plane, line, point, or axis. A datum feature is a physical feature of a part identified by a datum feature symbol and corresponding datum feature triangle. Degree of freedom In a very simple term, no. of direction in motion is referred to as a degree of freedom. A rigid body has 6 degrees of freedom […]
Symbols Some common symbols used in a Tolerance frame to specify a feature’s description, tolerance, modifier and datum references Free state Least material condition (LMC) Maximum material condition (MMC) MMR(Maximum Material Requirement) describes the condition where geometric characteristic has the most amount of material, it is very important in the assembly of two components. Projected tolerance […]
