摘要:
A facility for automated modelling of the cutting process for a particular material to be cut by a beam cutting tool, such as a waterjet cutting system, from empirical data to predict aspects of the waterjet's effect on the workpiece across a range of material thicknesses, across a range of cutting geometries, and across a range of cutting quality levels, all of which may be broader than, and independent of the actual requirements for a target workpiece, is described.

The invention provides an apparatus that holds and tilts a tool over a tilt range and substantially about a vertex. The apparatus includes a base having pivots defining a base line and a base pivot distance. The apparatus also includes first and second pivot arms coupled to the base pivots, and a tool holder having pivots coupled to the first and second pivot arms. The tool holder pivots defining a tool holder line having a pivot distance different than the base pivot distance. The tool holder is arranged for holding the machine tool. An intersection of the base line and a selected pivot arm defines a control angle, such that changing the control angle changes a tilt of the tool holder with respect to the base line, and correspondingly tilts a longitudinal axis of the tool substantially about a vertex.
摘要:
A system for controlling motion of machine tools and industrial robots. From the specification of a part to be cut or a path to be followed by a machine tool or robot, the system calculates for each axis, for each incremental step along the path, a position command (69), a time delay between successive position commands, and, optionally, a force command (68) based on a prediction of predicted resistive forces. Calculations are specified for precisely controlling velocity, acceleration, and jerk. The generated data is stored in a memory device and subsequently directed to the machine tool or robot.
