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 ...

Punch Dies: Knockout Round 1

A knockout has two roles, that is, the role of a stripper of a hole punching punch and the role of ejecting the product that has entered inside the die. Normally, a knockout is prepared with the same shape as ...

Automation Design Tips: Direction Change Mechanisms

The direction-changing mechanism is a mechanical component that alleviates restrictions such as arrangement or size on the mechanism design when transmitting forces from the driving shaft to the driven shaft. In other words, this mechanism changes the direction of forces ...

Component Alignment Technology

The parts feeder component alignment technology has been a mature technology since the industrial automation became popular since the early 1970s. But miniaturization of the parts to be aligned has increased the difficulty levels of alignment methods. For parts aligning, ...
