The goals of flow analysis can range from basic knit-line location prediction to measuring the exact displacement due to anisotropic conditions on a low-tolerance part. When performed early in the design process, users of the technology save thousands of dollars in startup costs, and thousands more by improving part quality, eliminating downtime and reducing cycle [...]
Some observations for improving scan quality through part mounting and orientation are given below: […]
Research has shown that strict RE methodologies may be devised for any classification of parts as opposed to a customized approach for each part (analogous to group technology manufacturing). […]
The best results in terms of accuracy and quality of surface finish are obtained using contact RE systems. Contact systems have several fundamental advantages over noncontact systems: treatment of surfaces to prevent reflections is not required, […]
Applications of RE in manufacturing are widespread. There are many instances in which an existing part or prototype requires reproduction, but lacks the computer data necessary to do so with accuracy and repeatability. […]
Reverse engineering (RE), the process by which an existing item is identically reproduced, becomes necessary when a physical prototype exists, but an accurate geometric data file of the part does not. […]
Data translation between CAD and CAM software applications is very high on the list of problems for buyers. The standard format IGES and the popular VDA in Europe are often flavored by software developers to fit their database structures. When choosing a system to fit your manufacturing needs, […]
While this may seem obvious to some, many companies become so impressed by the gadgets and features that software developers throw at them that they sometimes forget what they need. In order for design engineers to fully use CAD/CAM to make molds or parts, four key elements need to be in place: […]
To counter common accuracy and setup concerns in large machines, we must look at some of the necessary design characteristics of a large mold machining center. […]
Dealing with the sheer size and weight of a large mold can be a big challenge. This often leads to excessive labor, […]
