Configuring bend tables of a CAD sheet metal module
 |
A simple but working methodology about configuring the bend tables of a CAD sheet metal module is described in this article. The CAD user with a simple and workable method can accomplish correspondence between the CAD software and a CNC bending press. |
Non-standard metric screw thread geometry calculation
 |
Numerous applications require non-standard metric screw threads. Although non-standard screw threads should be avoided, when there is lack of an appropriate thread size many manufacturers (optical instruments, small size precision parts) use them. This article describes how to calculate such screw threads. |
Working with projection views
 |
The standard way to create an illusion of a 3-D image is to use the default drawing profiles or projection views. This article describes how to make these drawing profiles when your CAD program do not provide a preset function of projection views. |
Designing with Thermoplastics
 |
Today's technology has introduced a variety of new materials for almost every application. The most common non-metallic materials in engineering are the thermoplastics. This article describes a few principles when designing with engineering thermoplastics. |
Guiding lines for part modelling
 |
The CAD software has changed the way components are designed in the last five years, but definitely one of the objectives for every designer is the design efficiency. Simple guide lines can save a lot of time in the designing and redesigning procedure. Read this article and learn how. |
Timber constructions for packaging and transportation
 |
The timber is a native material which is used frequently in commerce for packaging and transportation. Timber constructions like timber boxes, pallets, stillages, and crates ones are often used for the transportation of items, machine tools, and equipment. |
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. |
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. |
