Spiral finishing
More processing efficiency
German software developer Schott Systeme has significantly improved CNC machining times by introducing three- and five-axis spiral finishing strategies into its "Pictures by PC" CAD/CAM software.
Spiral finishing is ideal for machining both steep and flat areas - for example in toolmaking, prototyping or model making - with a single, spiral-shaped tool path whose path distance is determined by the surface inclination. The spiral finishing path is generated from an outer guide curve to a point or center curve. The resulting single path ensures that the milling tool is in constant contact with the workpiece and that lift-off movements are reduced to a minimum. In addition, machining times are shortened and surface quality is improved at the same time.
Five-axis simultaneous spiral finishing is particularly suitable for machining surfaces with varying inclinations as well as undercut areas of a component, whereby the tool is automatically tilted for this purpose. If the lateral swivel range is restricted, a maximum tilt angle can be entered to limit the five-axis movement of the tool and holder. The three- and five-axis spiral finishing technologies, a proprietary development of Schott Systeme, can be applied to hybrid volume, surface and mesh models. pb
