Definition of Terms: Spherical Tolerance Zones

By Chris A. Lindenberger
Posted in

In our last blog post, we looked at the six common tolerance zones that appear in today’s engineering drawings. While these six make up the broad majority of tolerance zones in geometric dimensioning and tolerancing (GD&T), you may encounter another zone in a given tolerance scheme—the spherical tolerance zone. The American Society of Mechanical Engineers […]

Definition of terms- Tolerance Zones

By Chris A. Lindenberger

GD&T is a convention that gives the engineering world a tool that enables designed components to have both an unlimited variety of both geometric definition and tolerance. Consequently GD&T is about many things but it is ultimately about the disposition and appraisal of tolerance zones. This month our definition of terms will be about tolerance […]

Definition of Terms – Actual Local Size

By Chris A. Lindenberger

Today our definition of terms will focus on “actual local size.” This term refers to a group of values that can be assessed and applied to any feature of size, values that establish the small and sometimes minute irregularities about a feature’s geometry. To understand what this means we first need to go back to […]

In the world of engineering and manufacturing, we say that GD&T gives us the ability to explicitly describe both nominal geometry and its allowable departure or tolerance from that nominal value. One side of the convention allows for the definition of the geometry and the other allows for the definition of tolerance. Accomplishing the definitions […]

Times change, technologies change, and to stay on the proverbial cutting-edge means making important equipment changes when warranted. Our laser had served us well for 15 years. But as demand for our services has grown, the need for a larger, more efficient laser became apparent. We contacted our friend, Randy, at Englewood’s Action Machinery, discussed […]

Definition of Terms-Features and Features of Size

By Chris A. Lindenberger
Posted in

Today our featured GD&T term is “features,” which includes “features of size.” But before we jump into this we need to talk about a basic term or thing or maybe we’ll call it a concept, which is the term part. In GD&T a part needs to be thought of as an item, or two or […]

Definition of Terms- Basic Dimensions GD&T

By Chris A. Lindenberger
Posted in

In GD&T basic dimensions used to be a fairly simple thing to define. However, today, among other things, “Basic dimensions” are numbers on an engineering drawing that represent values of size in whatever the measurement system being used on the drawing is. Those values are used to describe the theoretically exact size, profile, orientation or […]
