- Simply put, engineering tolerance refers to the acceptable range of variation in a component or system’s physical dimension or property. Imagine you are designing a machine or constructing a building. Everything needs to fit together just right, down to the tiniest detail. That’s where engineering tolerance comes into play.
May 15, 2024 · By exploring the definition, types, and applications of engineering tolerance, we gain insight into its critical role in ensuring quality, functionality, and performance in engineering design and manufacturing processes.

Jul 5, 2023 · Tolerances define the acceptable variation in dimensions, form, orientation, and other critical parameters of a design. By establishing and managing tolerances effectively, engineers can achieve the desired balance between design requirements, manufacturing feasibility, and cost optimization.
What is Tolerance in Engineering? Tolerance is the total amount a dimension may vary and is the difference between the upper (maximum) and lower (minimum) limits. Because it is impossible to make everything to an exact size, tolerances are used on production drawings to control the parts.

A tolerance is a performance range you will keep to. The project tolerance definition I use in my book, Project Manager, is this: A project tolerance provides a boundary for the area of the project in which you can make changes without having to ask your sponsor’s approval. They define your zone of responsibility. Essentially, the sponsor delegates...
Tolerances can (and often should) be set for the project, for a stage and also at work package level, so they can become very detailed. The overall project tolerances should be agreed with the sponsor at the start of the project, so you know what parameters you are working to. They form part of the “contract” you have with the sponsor – and getting...
Talk to your sponsor. Discuss how much wiggle room you think is appropriate. A good starting point is +/-10% of the already-agreed timescales. They might want to set a lower figure for budget tolerances: project sponsors in my experience aren’t keen to go 10% over budget and not know about it.
Positive tolerances (the amount by which you can go over) are the most common. A positive tolerance is expressed as a positive percentage. It reflects how much more time/money/etc you can incur without having to ask permission to do so. Negative tolerances are less common, but you can still use them. I think the general feeling is who cares if you ...
The two most frequently used tolerances are budget and time, although PRINCE2®offers you a choice of seven tolerances: time, cost, scope, risk, quality, sustainability and benefits. Let’s look at those individually.
Have a conversation with your project sponsor during the Project Initiation phaseso you know what your acceptable freedom of action zone is.Document the tolerances agreed so you have a record.Track and monitor project performance against those tolerances so you can escalate when the project looks like it will go out of tolerance for any reason.May 9, 2022 · When it comes to engineering, every piece within a given product needs to be a certain size, with a limited and specific margin for error. These allowable differences in dimension are referred to as engineering tolerances.
Tolerance can be defined as the permissible deviation from the planned objectives, goals, or specifications of a project, without compromising its overall success. It serves as a buffer that allows for adjustments to be made without jeopardizing the project's ultimate outcome.
But in order to fully understand the dimensioning concept, we must learn about the engineering tolerances and how to correctly specify them on the engineering drawing. In this article, we will build upon dimensioning methods and go one step further; we will dive into the engineering tolerances.
