• Page 92: Polar Coordinates

  Polar coordinates If the production drawing is dimensioned in Cartesian coordinates, you also write the part program using Cartesian coordinates. For parts containing circular arcs or angles it is often simpler to give the dimensions in polar coordinates. While the Cartesian coordinates X, Y and Z are three-dimensional and can describe points in space, polar coordinates are two-dimensional and describe points in a plane.

  Layer settings As a rule, DXF files contain multiple layers, with which the designer organizes the drawing. The designer user the layers to create groups of various types of elements, such as the actual workpiece contour, dimensions, auxiliary and design lines, shadings, and texts. So that as little unnecessary information as possible appears on the screen during selection of the contours, you can hide all excessive layers contained in the DXF file.

  Characteristics of the fixed cycles The TNC automatically positions the tool to the set-up clearance before a cycle. Each level of infeed depth is milled without interruptions since the cutter traverses around islands instead of over them. In order to avoid leaving dwell marks, the TNC inserts a globally definable rounding radius at non-tangential inside corners.
