Many restaurants, independent hotels and timeshare resorts have much tighter budgets these days when it comes to purchasing seating for their properties. At the same time, there seem to be many “attractive” options available for their chairs, barstools and benches...
Having worked with attorneys in over 40 injury cases related to chairs (wood, metal, fully upholstered, plastic, aluminum, swivel, fixed mounted, outdoor), dining tables, occasional tables, bar stools, booths and banquettes; I felt the need to try and "clear the air" and save substantial time and resources for both plaintiff and defense sides moving forward.
"3D printing" or the more descriptive term - additive manufacturing (AM) - has received much publicity in recent years. What is this technology and what are some of its practical features? This blog is a summary of AM and its on-going development to make actual service components using metal alloys. Presented are selected portions of information provided in the two references cited.
Before expending the effort necessary to reverse engineer a device or object, it must be definite that the object under study is not covered by one or more patents. This avoids a dispute over patent violations. Once it has been established that no patent coverage exists, one can use multiple techniques to reverse engineer a product. These are summarized below:
The cracked tank was first inspected in the "as received" condition. In this condition it was cracked, but it was still whole. Next, the failed tank was separated by pulling it apart. This was done to expose the fracture surfaces of the main crack. This allowed for a complete failure analysis and for a determination of where the crack initiated.
Glass fractography is the most effective method for determining why a glass object, such as a bottle, failed. This technique consists of examining the fracture surfaces of the failure for artifacts such as Wallner lines and using them to trace the crack back to its origin. Once the origin has been identified, it can be examined in detail with a microscope to determine the cause of the failure.
Holistic Manufacturing™ is a revolutionary approach that focuses on the 'entire' manufacturing process, bringing together both technology and human systems in order to identify and reduce production variability. The result for manufacturing companies
