Fast product development

from Wikipedia, the free encyclopedia

The term Rapid Product Development (SPE) or English Rapid Product Development (RPD) refers to the continuous accelerated process chain of product development using modern methods and technologies such as. CAD , high-speed cutting (HSC), CNC micromechanics, Rapid Prototyping (Rapid Prototyping) and tool-less serial production - see: Additive fabrication and rapid manufacturing (dt. Rapid manufacturing ). It is a sub-area of production automation with specialization in accelerating the development process and complexity of the geometry of the component shape.

Big components

In the case of large components, various processes can be integrated into this process chain for the production of small quantities on the basis of existing physical master form models. This can u. a. Methods such as the cold spraying , the sand mold casting , the precision casting , the vacuum casting , the laser sintering or the metal spray process be.

Small components

For small components (micro-components), the internationally patented RMPD process family (RMPD = Rapid Micro Product Development ) developed by microTEC in Germany in the 1990s already offers technologies that enable large and small series production directly from the CAD data - without tools - allow. Three-dimensional components are produced, some of which could no longer be molded with tools. In this way, multifunctional systems are also produced in series, which are either too expensive in individual assembly or cannot be produced at all.

Mark

The use of RPD is characterized by the time and cost savings that can be achieved during the development process. These savings can amount to approx. 30 to 70 percent of what is required when using the classic approach.

Another characteristic for the consistent use of the RPD is the consistent use of a 3D geometry data set for all elements of the "product development" process chain and, with the RMPD technologies, the possibility of directly integrating circuit layouts (E-CAD / OrCAD) data to the overall system simulate and optimize and then produce them in batch (several parts in parallel) based on this data .
