Which of the following option is incorrect about interchangeability?
Which of the following option is incorrect about interchangeability.
Explanation: An interchangeable part is one that can be replaced with a similar part manufactured to the same drawing.
It can be used in mass production with an economic oriented approach.
Assembly time decreases as mating parts are interchangeable..
What is it01?
Explanation: ‘IT’ refers to the standard tolerance which belongs to any standard grade of tolerance. Tolerance grades are designated by ‘IT’ letters followed by a number. For example, IT01 is a tolerance grade.
What is advantage of interchangeability?
Interchangeable parts are parts that are, for practical purposes, identical. They are made to specifications that ensure that they are so nearly identical that they will fit into any assembly of the same type. One such part can freely replace another, without any custom fitting, such as filing.
What is tolerance answer?
1 : capacity to endure pain or hardship : endurance, fortitude, stamina. 2a : sympathy or indulgence for beliefs or practices differing from or conflicting with one’s own. b : the act of allowing something : toleration.
What is tolerance chart?
Values in Process Tolerance Charts typically represent the BEST attainable values. They also represent single-feature relationships. We refer to these intra-feature process planning.
How is tolerance calculated?
The span is the algebraic difference of the input upper and lower range values divided by 100. If the tolerance is based on output, then no conversion is required. The %URV criterion is the upper range value divided by 100.
How many types of tolerance are there?
Today, there are 14 types of geometric tolerances by the number of symbols, and 15 types based on classification. These are grouped into form tolerance, orientation tolerance, location tolerance, and run-out tolerance, which can be used to indicate all shapes.
What is basic tolerance?
It is the basis from which permissible variations are established by tolerances on other dimensions, in notes, or in feature control frames. In short, tolerances are not applied directly to basic dimensions because the tolerances are expressed elsewhere, usually in feature control frames.
Which of the following is incorrect about tolerances Mcq?
6. 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 is tolerance of a material?
ASME Y14. 5M defines tolerance as “the total amount a specific dimension is permitted to vary.” Tolerance is the difference between the maximum and minimum limits. This can be shown as upper and lower limits or an allowable amount above and below a nominal dimension.
What is the number of fundamental deviation in the BIS system?
25There are 25 fundamental deviations are there to fit the shaft in a hole with these 25 allowable deviations.
What is the purpose of interchangeability?
Interchangeable parts, popularized in America when Eli Whitney used them to assemble muskets in the first years of the 19th century, allowed relatively unskilled workers to produce large numbers of weapons quickly and at lower cost, and made repair and replacement of parts infinitely easier.
What is tolerance explain its types?
A tolerance is an acceptable amount of dimensional variation that will still allow an object to function correctly. Tolerances. Three basic tolerances that occur most often on working drawings are: limit dimensions, unilateral, and bilateral tolerances. Tolerances.
What are the 2 types of tolerance?
There are two types of drug tolerance: physiological and behavioral. Physical tolerance occurs at the cellular level. The body increases the rate at which the drug is broken down (metabolized).
What is meant by roughness?
Surface roughness often shortened to roughness, is a component of surface texture. It is quantified by the deviations in the direction of the normal vector of a real surface from its ideal form. If these deviations are large, the surface is rough; if they are small, the surface is smooth.
What is the purpose of tolerance?
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 is h7 g6?
Close running fit for running on accurate machines and for accurate location at moderate speeds and journal pressures. H7/g6. G7/h6. Sliding fit not intended to run freely, but to move and turn freely and locate accurately.
What is a h7 tolerance?
In other words, H7 tolerance works with the inner dimension (ID) of the cylinder. … For example, an h6 tolerance which says 10.000+0.000/-0.011 means that the tolerance for shaft can be 0.011 mm smaller than base, but no larger. The h6 tolerance is a measure of the cylinder’s outer dimension.
