* Three-dimensional Tracing / Digitizing. The profile contouring is carried out by three axes which are controlled by the CNC. There must always be a surface for the probe to touch. The maximum slope of this sweeping surface depends on the sweeping feedrate and the nominal deflections. The greater the sweeping feedrate the flatter the surface must be. The contour, defined by function G27, may be either closed (where the initial and final points are the same) or open (where the initial and final points are not the same). With this option it is possible to carry out a continuous digitizing of the model which will be controlled by the CNC depending on the values assigned to the digitizing parameters.
