Socket button head cap screw: The elegant screw
 |
The socket button head cap screw is not suggested for use in critical high strength applications, but with no doubt is the most elegant of all the common fasteners. Read this article to find why and how this fastener will make your designs more elegant than before. |
Turning of rods
 |
Rods are small diameter shafts with relatively large length. They are used in many applications (holding a part, offsetting, adjusting, etc). Although it seems easy to design a rod, in reality, in order to design the correct rod for the application one needs to know a few versions of this simple component. |
Indexing with servo motors
 |
Using servo motors for indexing and controlling the rotation or transportation is common in fixture, packaging and automation design. This article describes what really a design engineer needs to know for a servo motor unit in order to complete his designs. |
Transportation tracks for plastic components
 |
In many applications, especially in auto-feeding and automatic assembly operations, the plastic workpieces or products are transferred to final assembly position with the aid of feeding tracks. The feeding tracks transport the plastic components with the simplest way using pressurized air as the convection media. |
How to make circular workpiece path for feeding tracks
 |
In many applications, especially in auto-feeding and automatic assembly operations, the workpieces or products are oriented relative to final assembly position with the aid of circular feeding tracks. The major issue with this kind of feeding is the design of a circular workpiece path with the correct size. |
Using steel balls, oil, PVC paste and grease in fixture design
 |
Steel balls, oil, PVC paste and grease (hydraulic pressure) actuated by hand produce fixture design capable for high clamping forces, simplified and low cost manufacturing. This article describes the application of the above elements (parts and materials). |
Coupling Parts made from Hard and Soft Materials 2
 |
Frictional units, shafts and hubs, and a plenty of design cases contains coupling parts made from hard and soft materials. The principles stated in this document explain the mechanism of wear formation, and the techniques to eliminate it. |

Layering CAD files for CAM
 |
CAD-CAM software and modern machine tools have changed dramatically the manufacturing possibilities in the last decades. Although CAD-CAM software facilitates and simplifies the design-manufacturing procedure, the CAD users must deliver their designs (2D-3D data) properly in order CAM users spent less time in programming (NC code). |
Hammer action
 |
In manual operating fixtures is difficult to apply a large clamping pressure through cam (or wedge) actuating mechanisms. The reason is friction due to small cam angles. The solution is to incorporate striking or hammer action. |
