Splines are interpolated as tangentially connected arcs within the given tolerance.Įllipses are interpolated as arcs with the given number of segments (per full ellipse).Īrcs can optionally be interpolated as lines with the given segment length if the targeted controller does not support circular movements. The safety Z level is used at the beginning and end of the program as well as before tool changes. The output file can be set here or later when the output is generated for the first time. Adjust the parameters of the selected configuration (CAM > CAM Configuration.):.QCAD/CAM computes the tool path of the tool center based on the tool radius automatically in this case and outputs the appropriate offset coordinates. This configuration can be used if no G41/G42 commands are available or G41/G42 should not be used. This configuration can be used when the controller supports the commands G41 and G42 for radius compensation. Choose the desired configuration (postprocessor) at the top left:.In this example, these are all the contours in the drawing.

Select all the contours that are to be processed with the same machining parameters and the same tool.The circle is not a polyline, and may have its start point at any point. With the function Select > Select All all start points of all contours can be highlighted (red): Here the center of the lower segment is selected:Īll contours are now ready for processing. This can be an existing node, or any other point on the polyline. For our example, this is not the case for the inner contour (the red reference point is the start point of the selected polyline):īy right-clicking on the contour, the start point can be set to another position:Ĭlick on the new position of the start point. This must be a start point at which the contour can be approached using a lead in. All contours must have a suitable start point.In the first step, the polylines are created which represent the geometry that has to be cut:.Creation, Preparation and Selection of the Geometry
