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, […]
Following is a list of seven daily habits to include—the most mentioned, or in some cases, the most vehemently defended. Here they are in order of frequency: […]
Ultrasonic units with super fast, very short strokes, provide virtual unrestricted finger tip control. By comparison, regular reciprocating tools—such as air-driven or electric flexible shaft-operated die profilers—are more restrictive in movement and less flexible to handle. Nevertheless, die profilers and/or various other filing machines are great for medium to large mold details and when used [...]
We need to stay objective and remind ourselves that ultrasonic polishing is not for everyone. Frequently, ultrasonic systems are perceived to take care of all polishing problems. This is not so. Ultrasonic polishing is not a cure-all for every mold and die shop that does in-house polishing. […]
By comparison to conventional die profilers, as well as air-powered lapping machines that may have a stroke length of up to ¼ inch, the reciprocating action of an ultrasonic unit ranges only from .00004 to .00012 inches. […]
