Compressed Air Systems: Pipe Diameter Sizing

Diameter for factory-wide air distribution plumbing is sized with increased future demands in anticipation. Additionally, the pipes accumulate scales and specks of dust on the internal walls from long-term usage and the flow efficiency will be reduced. For these reasons, ...

Compressed Air Systems: Distribution Plumbing Design

On factory floors, compressed air is often perceived as free, therefore, compressed air plumbing design may be somewhat neglected. However, the quality of plumbing designs largely affects the air quality and air pressure losses, causing machine operation instabilities. Here, compressed ...

It’s Spring Time Part 4: Energy Absorption, Natural Frequency, and The Surging Phenomenon

In our last post on the spring series, we examine energy absorption, natural frequency, and the surging phenomenon. When you apply a load on the spring, deflection (deformation) occurs in accordance with Hooke’s law. (See [Fig.1].) When you quickly release ...

It’s Spring Time Part 3: Load-Deflection Relationships

We’ve been introduced to materials and characteristics of springs. Let’s dive into helical springs more deeply specifically compression and extension springs. Their load deflection relationships will be evaluated for both. Load-Deflection Relationship for Helical Compression Springs When the load on ...

It’s Spring Time Part 2: Types of Springs

As we have been introduced to springs, as promised, it is time to dive into the types of spring shapes and load-deflection characteristics. Learning about these characteristics can help you narrow down your design decision on the use of springs. ...

Swaging: A Deformation

In the simplest of terms, products are generally made by functionally assembling various parts. Product design and assembly/production technology enabling stable product quality at low cost (in other words, products that are easy to make) are key to this assembly ...

A Standard Comparison: JIS vs. AISI/UNS

First things First and Disclaimers Steel is a complex engineered material that comes in almost an infinite variety of chemistries and designations, each tailored to a specific application. The material science is complicated enough by itself, to say nothing of ...

Keep It Tight: Fastener Techniques

“Screws” are the most widely used and imperative components for machine system manufacturing. They are classified by shapes, sizes, and strength (class) according to the standards of JIS, ISO etc. In this post, we will cover how screws become loose ...
