Milling prototype machine

These cutting operations are usually used only for machined prototypes, or very low volume production of simple shapes. High speed routing is sometimes used for slotting or gate removal on injection molded products. Standard end mills (two-flute), cir-...

Rapid prototyping is an "additive process, combining layers of plastic to create a solid object. In contrast, most machining processes (milling, drilling, grinding) are "subtractive processes that remove material from a solid block. 

Since USM mills can be used on these multipurpose milling machines, the micro milling process is considered a flexible manufacturing process. In addition, the process is characterized by low setup costs, unlimited part materials, and a high material removal rate (Ozel et al. 2011). It is, for example, used to machine small features in molds used for mass production (e.g., microfluidic devices), to structure medical implants for better biocompatibility, to generate deep x-ray lithography masks, and to manufacture prototypes rapidly as well as efficiently (Aurich et al. 2012). 

Tools are objects that help humans perform work. They can be very simple like a hammer or very complex like a computer-controlled milling machine. The simplest tools used by hiunans during prototyping are common hand tools. Power equipment performs other, more complex processes. 

The feasibility of the technique having been established, it was applied to the fabrication of the base, column and overarm of a horizontal milling machine. - The drives, knee, spindle etc. were unchanged and hence the dimensions of the structural parts that interface with the unchanged parts were identical to those of a production model. Figure 1.13 shows the main features of the prototype. As this was to be manufactured on a one-off basis, all the double-containment joints and the V-ways were machined from solid.
