How Modularity Supports Industry Transformation
This whitepaper helps companies navigate the process for selecting enterprise resource planning (ERP) solutions for the aerospace & defense industry.
Tactile and optical measurement techniques each have their strengths, and there are certainly measurement tasks that require only one of the two.
In systems designed for automated precision measurement, users are typically balancing accuracy of measurement, speed of operation, and cost to purchase and operate. The need for tradeoffs and sometimes-difficult choices will always be with us, but the introduction of multisensory measurement throughout the last several decades, along with subsequent improvement in its capabilities, offers opportunities for improvement in all three areas.
There are two available contact-scanning technologies: passive and active. Passive scanning probe heads use springs to hold the stylus in its neutral position and strain gauges to measure deflection.
Both record surface data based on the movement of a stylus connected to a scanning head. The difference is what goes on inside the scanning head. The distinction between touch-trigger (single point) measurement and scanning is well known. Touch trigger has been described as a “woodpecker” approach measure a point, move to another location, measure again, and repeat until the job is done. The surface or feature condition between the points that are actually measured may be estimated by interpolation, but significant deviations can be missed. Also, because each measurement is a discrete operation and the measuring head must be repositioned to measure the point, the process can be very slow. Scanning, on the other hand, is accomplished with a fluid and continuous movement that can quickly and accurately measure hundreds or thousands of points along a path as the stylus moves across a surface. But while all scanning technologies offer advantages over single-point measurement, all scanning probe heads are not the same.
Is conversational programming a necessary component of today’s Manufacturing environment?
Conversational programming is an evolution of partprogramming. It takes what is known and simplifies it for all users. The requirement to study the art of G-code programming is replaced by the need to be able to teach variables off a blueprint into a single screen on your CNC. The important thing is that Users do not need to be well versed in any particular brand of G-code programming. Therefore, in just an hour or two any operator can be taught how to program well in Conversational Programming.
An overview of system level design for wireless communications equipment.
This white paper presents an overview of system level design for wireless communications equipment. It will be useful not just to those involved in the development of new communications systems, but also to designers of new products using existing systems, or anybody seeking to develop new architectures and/or components to reduce product cost and/or size. It also describes the benefits and implications of developing highly integrated System on a Chip (SoC) solutions, which dominate in today's high volume communications products.
A description and comparison of CVD diamond coated tooling.
The technology for the chemical vapor deposition (CVD) of pure diamond coatings on rotating cutting tools has developed rapidly during the past several years. Tungsten Carbide round tools are regularly being coated with continuous, well adherent, diamond films that improve machining performance and increase tool lifetimes in composite materials by 15 to 30 times over uncoated tools. This paper reveals the process methods involved in CVD diamond film growth on tungsten carbide tool surfaces and the unique properties of diamond thin films.
Read what Tara Meinck, Application Engineer with Spirol Int’l Corp. USA says about ensuring bolted joint integrity.
Compression Limiters are used to protect plastic components in bolted joints and maintain a threaded fastener’s clamp load by eliminating plastic creep. To function properly, bearing surface beneath the bolt’s head must extend over the Compression Limiter to contact the plastic component. If this bearing surface is too small, the host component may not be retained by the bolt resulting in a poor joint.
