Steel is present in nearly every aspect of modern life, from infrastructure, vehicles, and appliances to advanced technology and aerospace. It stands as one of the world’s most widely used engineering materials. However, not all steels are identical; their compositions and intended applications vary greatly. Selecting the appropriate steel type and grade is a vital decision for any engineering or manufacturing project. What is Steel? Steel is an alloy, which means it is made from a mixture of elements rather than a single element. The base element in steel is iron, while other ......

UNC and UNF are both threads defined in the Unified Thread Standard to specify their tolerances and designations. What are the differences between UNC and UNF threads, and which one to use? This article will focus on their definition, uses, differences, standard, and dimensions chart. What Is a UNC Thread? UNC stands for Unified National Coarse thread, a standardized thread form under the Unified Thread Standard (UTS) developed primarily in the United States. UNC threads are characterized by a coarse pitch, meaning they have relatively fewer threads per inch (TPI) compared to f......

In modern CNC machining, G-codes and M-codes form the backbone of programming instructions that control how a machine operates. Whether you’re using a milling machine, turning center, or multitasking CNC, mastering these codes is essential for precision manufacturing. Among various CNC control systems, Fanuc is one of the most widely used in industries worldwide. This article provides an in-depth look at Fanuc G codes, their applications, and where you can find a complete G code list, Fanuc M code list, and Fanuc lathe M codes for efficient programming. What Are Fanuc G Cod......

Choosing the right method for defining the location of features on a part is vital for engineering, inspection, and manufacturing teams. Two approaches dominate this space: traditional coordinate dimensioning and Geometric Dimensioning and Tolerancing (GD&T) position control. Understanding the advantages and limitations of each approach leads to better part quality and more efficient production. GD&T Position vs Coordinate Dimensions, Which is Better To Use? Most engineers, designers, inspectors, and machinists are familiar with coordinate dimensioning and tolerancing......

Geometric Dimensioning and Tolerancing (GD&T) is a detailed system used in engineering and manufacturing to define the allowable variation in part geometry. As part designs become more intricate, advanced GD&T techniques are needed for proper control. Among these, composite position tolerancing and the use of two single segments often arise as topics of focus. Understanding how these two approaches function, and how they differ, can help ensure proper fit and function of assembled parts. What is Composite Position Tolerance in GD&T? Composite position tolerancing invol......

Nails are an important fastener that is often seen in wood and other constructions. To find out the correct nail for specific uses, knowing its sizes is necessary. Here we introduce the parts and types of nails and the standard nail size chart to determine the diameter, gauge, and length. What Is a Nail Fastener? A nail fastener is a simple but essential tool used in woodworking, construction, and many other industries to join materials together securely. It is typically a slender piece of metal, often steel, with a sharp pointed end to penetrate materials and a flattened head on ......

Have you ever looked at a technical drawing and seen abbreviations like DRG, CSK, SK, or SQ and wondered what they mean? In the world of CNC machining, mechanical design, and engineering drawings, these shorthand notations are essential for conveying complex information clearly and efficiently. This article breaks down the most common abbreviations and symbols found on engineering and technical drawings, explains why they are used, and offers a handy reference table for quick lookup. Why Use Abbreviations and Symbols in Engineering Drawings? Technical drawings are critical blue......

Multi Jet Fusion (MJF) is a newer addition to 3D printing technologies. It is capable of creating plastic components with high durability and accuracy. In this post, we will focus on MJF 3D printing technology, including its principles, processes, equipment, materials, and comparisons with other printing techniques. What Is Multi Jet Fusion 3D Printing – MJF 3D Printing Definition MJF 3D printing is one of the additive manufacturing technologies created by HP that uses a powder bed method to construct components. MJF has been under development since 2016, and within such a short t......
