Abstract
A method and system for describing a three-dimensional path of an industrial processing machine, such as a machine tool, a robot and the like, is disclosed. According to the disclosed method and system, the path is described by a curve that includes at least one interpolation, wherein at least one interpolation parameter is a function of an angle along the three-dimensional path.
Claims15
A method for controlling an industrial processing machine, comprising the steps of:
- defining a contour of a workpiece to be machined in a coordinate system;
- defining at least one continuous three-dimensional machining path in a cylindrical coordinate system, the cylindrical coordinates being a rotation angle of a tool relative to the workpiece, a feed distance of a tool relative to the workpiece, and a distance of the tool from the origin of the coordinate system;
- performing at least one interpolation along the continuous three-dimensional machining path;
- and
- guiding a movement of the workpiece or tool, or both, along the interpolated continuous three-dimensional machining path,
- wherein the at least one interpolation along the continuous three-dimensional machining path is a function of the rotation angle.
A processing machine with a tool for machining a workpiece, said processing machine comprising a controller that defines, based on a defined contour of a workpiece to be machined in a coordinate system, at least one continuous three-dimensional machining path in a cylindrical coordinate system, wherein the coordinates of the cylindrical coordinate system are a rotation angle of the tool relative to the workpiece, a feed distance of the tool relative to the workpiece, and a distance of the tool from the origin of the coordinate system;
- performs at least one interpolation along the continuous three-dimensional machining path;
- and guides a movement of the workpiece or tool, or both, along the interpolated continuous three-dimensional machining path, wherein the at least one interpolation along the continuous three-dimensional machining path is a function of the rotation angle.
