2 FACTORS AFFECTING MINIMUM BEND RADIUS
In this video we discuss the two main factors that affect the minimum inside bend radius for sheet metal or formed plate designs. We cover some basic terminology regarding thickness, look at what happens if the bend radius is too small, and go over inside bend radius tables for various metal alloys and thicknesses.
HOW TO USE MMC AND LMC TO DETERMINE TOLERANCE VALUES
This week’s engineering tips video responds to a question submitted in the comments asking what the benefit of using MMC and LMC versus standard tolerancing. In this video we demonstrate how MMC and LMC can be used at the interface level between two components to help determine what the nominal dimension and tolerance should be for a mating component using a simple press fit pin into a plate example.

3 ENGINEERING DRAWING PITFALLS YOU SHOULD AVOID
In this video we will be covering three common drawing pitfalls that designers should avoid when creating engineering drawings. These pitfalls contribute to confusion and worse yet, sometimes cause conflicts within the drawing.
WHAT IS SADDLE-ON AND SADDLE-IN PERTAINING TO MANIFOLD DESIGN
In this video we cover what is saddle-on and saddle-in as it pertains to manifold design. We discuss the basics of a manifold, along with the differences between the saddle-on and saddle-in connection types between branch and header.
2 SIZE DESIGNATIONS DESIGNERS MUST KNOW
In this engineering tip we cover the two size designations designers must know. That is maximum material condition and least material condition. We cover the symbols used for these designations, what they mean, and how they are applied to engineering drawings for both external and internal features. We also discuss the benefits of thinking in terms of max material condition and least material condition when performing tolerance stack ups and fit evaluations.
WHAT IS FEA AND HOW IT WORKS
In this video the basics of Finite Element Analysis (FEA) are presented, along with how FEA works. The method by which FEA subdivides the geometry into smaller pieces known as elements through a process known as meshing is discussed. An example using a simple round steel bar with an axial force applied is used to demonstrate how FEA solves for displacement, strain, and stress.
3 THINGS TO AVOID WHEN DESIGNING GUSSETS
This video presents three things to avoid for improving your gusset designs and help avoid fit up issues with the fabricator. The first is to avoid having gussets with very similar, but different, leg lengths. This can be confusing during fabrication and result in orientation issues. The second is to avoid sharp ends on the gussets. Sharp ends can be difficult to weld and can result in quality issues. The better approach is to blunt the sharp ends of the gusset. Finally, add a chamfer to provide weld clearance or to provide clearance with inner radii associated with structural shapes like I-beams.
CIRCULARITY, CYLINDRICITY, AND CONCENTRICITY
This video explains the differences between the following GD&T controls: Circularity, Cylindricity, and Concentricity. Circularity is a 2D form control (aka Roundness) that ensures a shape is perfectly round within a specified tolerance. Cylindricity is a 3D from control that applies to the entire surface of a cylindrical part or feature. Concentricity is a 2D location tolerance that ensures alignment between axes of cylindrical features.
TOP 3 ADVANTAGES OF COUPLING DESIGN AND SIMULATION
Whether it be a product line extension, product improvement, or a completely new design coupling design and simulation using FEA or CFD brings a myriad of benefits to the table. Most namely are the advantages of simulation over physical prototyping. Physical prototype and testing is tough, time consuming, and costly. Simulation has multiple advantages over physical testing and prototype, however, among all these benefits three .... click HERE to read more.
USING CFD TO SIMULATE 3 KEY VALVE METRICS QUICKLY
CFD simulation can be used to simulate your valve design early in the development process. Key metrics such as pressure drop, flow rate, valve forces, and fluid velocity can quickly be simulated. Knowing these performance metrics early in the design process can reduce the design and testing effort significantly.
Using the 3D CAD model of the current valve design as a starting point, the flow through the valve can be simulated. From the flow ... ckick HERE to read more.
