Datum Reference Frame (DRF) in Geometric Dimensioning and Tolerancing (GD&T): An explanation with figures

,
GD&T DRF Part with Constraints

A datum reference frame is a coordinate system against which the geometric dimensions and tolerances of a part are defined. The main function of the datum reference frame is to specify a foundation for the inspection of the part. It is the common coordinate system of all tolerance zones. Without this common coordinate system, product definition is unclear, rendering the inspection results unreliable. Read More

Comparison of tolerances used for coaxiality control: Position, Concentricity, Circular Runout and Total Runout

,

Coaxiality conditions can be vital for shafts supporting heavy and varying loads, such as car and truck axles, electric motors, generators and pumps. There are four different types of tolerances for defining coaxiality controls: Position, concentricity, circular runout and total runout. This post proposes brief and practical definitions regarding which type of tolerance to choose for certain applications as well as the advantages and disadvantages to each. For more information, refer to the ASME standard [1] and other related reference articles [2]. Read More

Surface Inspection Annotation

BuildIT surface inspection annotation of points

BuildIT allows users to perform quick and easy inspections. It also enables users to perform analysis and produce reports that are both detailed and simple to generate.

The Surface Inspection Annotation command is a good example of BuildIT’s ease of use. Without performing a complete analysis on a part or an entity you are inspecting, you can evaluate a single measurement at a time. This command also allows you to manually annotate measurements in order to convey information in a way that is clear and simple. Read More

Building Photogrammetry: Comparing Camera Results of iPad VS DSLR

DSLRfig1

If 800 people are working on the iPhone camera, would this mean that smartphone / tablet cameras will soon match the performance of DSLRs?

The short answer is “No”, as long as the camera sensor size is not increased.  A larger camera sensor allows the capture of more light and reduces noise levels. Their applicability to smartphones / tablets will always be limited, however, since a larger sensor size would also require a larger lens, which would not be very practical for a smart device.
