High-speed machining (HSM) is usually associated with high-speed spindles (15K to 40K rpm) and higher feedrates. It is also referred to as high velocity machining. They are one in the same, as both represent machining components in the most accurate and shortest cycle times. […]
Recent years have seen a number of articles on the benefits of closer integration of CAD and CAM. Of course, integrated CAD/CAM systems from a single company have been available since 1972. The new trend is for the integration of CAM systems into CAD software from a completely different developer. The decision for moldmakers is [...]
A better approach to CAM software development is to follow the logic that machinists themselves use when deciding how to machine a complex 5-axis part. Instead of fragmenting advanced 5-axis functionality, why not present programmers with a single programming process that is familiar and easy to understand? […]
Moldmakers were the first wave of manufacturers affected by the outsourcing trend that pushed manufacturing into China. But now we’re seeing that business is coming back . Culture and geography have helped provide a temporary stay for domestic moldmakers. But make no mistake, China and other offshore manufacturing industries will fix these problems, and they [...]
Examining the mold development process itself is equally important for determining how specific tools and development platforms can benefit a moldmaking operation. Such an assessment will reveal a fact that most moldmakers already know: […]
The challenge for moldmakers with multi-axis machines is to generate CNC programs that fully exploit the capabilities of these machines. The goal is to take full advantage of the additional axes of movement—whether on the table or in the tool head—in the most efficient manner while producing an outstanding surface finish. […]
The old fashioned way but still being used by some mold manufacturers. Designing a mold cavity and core in 2D. Some mold designers may use different procedure. You can use Autocad, UGNX, ProE, or just plain tracing paper and pencil in this mold design tutorial. 1) Calculate for the mold dimension using the shrinkage factor. [...]
Without the CNC programmer, any modern plastic injection mold making operation grinds to a complete stop-quickly! Just consider for a moment just how many machines use the CNC programmer…. […]
Fixed Clamping PlateHolds The fixed side of the mold to the fixed platen of the injection machine […]
This checklist can be used as a general reference guide for injection mold design engineers. It is divided into 3 parts of a mold design process. Part 1 – Requirements to start your mold design: Check the injection machine where the mold is to be mounted. This will help you decide the size and structure [...]
