2D A 3D MILLING

Milling is the most common and most versatile technology for the processing of plastic materials from wood to wood. An example of a suitable modeling cutter that suits both the workspace size and the quality control program is the Austrian StepFour. A 100W high-speed milling spindle with milling cutters of 0,5mm diameter ensures the finest detail. The input data file is a autocad drawing in .dxf format with predefined levels in the gradient, hole, and circumference order. The aperture and perimeter resolution is required for input in the control program, where the internal and external contours are defined to define the cutter path. The reason is clear - if you cut the windows with a 1mm diameter cutter, the cutter path must be 0,5mm in internal contour.

The advantage of milling is the accuracy of the processing of a wide range of materials, the disadvantage being time consuming, spindle noise and ubiquitous fine sawdust. Most standard modeling cutters allow you to purchase and install a 3D superstructure of the control program, then some 3D files can also be processed with the advantage of dynamic spindle motion even in the Z axis. Example of use is the production of terrains or reliefs. Since this is not a full-scale processing of spatial files, this method is referred to as 2 and 1/2D. Example 2 and 1/2D milling can be seen in pictures from the Křivoklát plastic model.
