Which of the following is incorrect about tolerance?
Which of the following is incorrect about tolerances.
Explanation: Loose tolerance results in increase in cost, assembly problems and poor performance of the product.
Tight tolerance results in unnecessary machining and inspection time..
What are the 3 types of tolerances?
Three basic tolerances that occur most often on working drawings are: limit dimensions, unilateral, and bilateral tolerances. Three basic tolerances that occur most often on working drawings are: limit dimensions, unilateral, and bilateral tolerances.
What is basic tolerance?
Basic dimension: A basic dimension is a numerical value used to describe the theoretically exact size, profile, orientation, or location of a feature or datum target. The tolerance associated with a basic dimension usually appears in a feature control frame or a note. …
How do you determine flatness tolerance?
Gauging / Measurement: Flatness is can be measured using a height gauge run across the surface of the part if only the reference feature is held parallel. You are trying making sure that any point along the surface does not go above or below the tolerance zone.
What is tolerance answer?
Most recent answer Tolerance refers to an attitude of openness and respect for the differences that exist among people. Meaning of tolerance can be described in two directions, first when we consider about accepting people for who they are and second means treating others the way you would like to be treated.
How is tolerance decided?
The tolerance is the difference between the maximum and minimum limits.” This can be shown as upper and lower limits (0.2500over0. … This range of allowable dimensions is the tolerance band. The larger the difference between the upper and lower limits, the larger the tolerance band, referred to as a “looser” tolerance.
What is a h7 tolerance?
International Tolerance grades For example: H7 (hole, tapped hole, or nut) and h7 (shaft or bolt). H7/h6 is a very common standard tolerance which gives a tight fit. … For a shaft of the same size, h6 would mean 10+0−0.009, which means the shaft may be as small as 0.009 mm smaller than the base dimension and 0 mm larger.
What is double dimensioning?
4.5/5 (47 Views . 14 Votes) Dual dimensioning is the drafting practice of using multiple units of measure in a dimension in the same direction of a feature. SolidWorks and many other CAD programs support dual dimensioning.
What are GD&T symbols?
Geometric Dimensioning and Tolerancing (GD&T) is a system for defining and communicating engineering tolerances. It uses a symbolic language on engineering drawings and computer-generated three-dimensional solid models that explicitly describe nominal geometry and its allowable variation.
What is tolerance chart?
A tolerance chart is a graphical representation of a process plan and a manual procedure for controlling tolerance stackup when the machining of a component involves interdependent tolerance chains. … A special path tracing algorithm is used to identify tolerance chains from this graph.
What is tolerant mean?
inclined to tolerate1 : inclined to tolerate especially : marked by forbearance or endurance tolerant parents a culture tolerant of religious differences. 2 : exhibiting tolerance (as for a drug or an environmental factor)
Why do engineers use tolerances?
Tolerances determine exactly how much room for error you have when you manufacture each part. When you appreciate the vital role that tolerances play in the manufacturing process, you’ll design higher quality products and make fewer costly manufacturing mistakes.
What does tolerance mean in engineering?
Engineering tolerance is the permissible variation in measurements deriving from the base measurement. Tolerances can apply to many different units.
What is an example of tolerance?
Tolerance is being patient, understanding and accepting of anything different. An example of tolerance is Muslims, Christians and Athiests being friends. The capacity for or the practice of recognizing and respecting the beliefs or practices of others. The capacity to endure hardship or pain.
What is the purpose of tolerance?
TOLERANCE :Tolerance is the allowable variation for any given size in order to achieve a proper function. Tolerance equals the difference between lower and upper limit dimensions.
Do you inspect basic dimensions?
You shouldn’t be glossing over anything. Basic dimensions are used to validate part geometry as defined in feature control frames. If there are features that have basic dimensions defining their location or orientation without an associated feature control frame, then the print IS improperly dimensioned.
