Pickling is a metal cleaning process using acidic baths to remove impurities. It’s simple, affordable, and improves corrosion resistance. While effective, it has drawbacks like solution degradation and hazardous waste production.
Surface finish describes texture requirements for surfaces, including roughness (small defects), waviness (larger imperfections), and lay (pattern orientation). Symbols on technical drawings specify these textures and necessary manufacturing processes, helping to avoid extra costs and delays.
J threads, are modified UN and metric threads where the external thread features a more rounded root profile, reducing stress points and enhancing durability under vibration, fatigue, and temperature changes.
Minimum wall thickness in CNC machining affects component performance. Understanding material-specific limits helps balance mass reduction with manufacturability.
This article explains the differences between cut and rolled threads. Cut threads are made by removing material, which can weaken the body. Rolled threads are pressed into the body without removing material, enhancing fatigue properties.
An undercut is a machined feature providing clearance for mating parts or tools. Common uses include seating shoulders and thread relief for cutting tools.
A fillet weld is a type of weld that is used to join two metallic components, typically at right angles to each other, forming an L shape. The weld is triangular in shape and may have a concave, flat or convex surface depending on the welder’s technique. It is one of the most common types…
Stress (N/mm^2 or MPa) can be defined as the internal resistance of a structure or body when an external force is applied. Therefore, stress is calculated as the force applied (N) divided by the area (mm^2) over which the force is distributed. There are five distinct categories of stress: Similar to accumulating forces, stresses can…
In-plane loading on a bolt occurs when forces are applied parallel to the plane in which the bolts lie. This contrasts with out-of-plane loading, where the forces are applied perpendicular to this plane. As a result of this, in the case of in-plane loading, the bolting group does not experience any bending loads. In-plane rotation of…
A flanged bolt coupling is a mechanical device used to connect two shafts together at their ends for the purpose of transmitting power. When connecting shafts using a flanged bolt coupling (like the example shown below) the torque load across the connected shafts generates a shear force in the bolts. In this application, it can…
