Embodiment Construction

[0038] The present invention provides a new, open, software architecture for digital control interfaces. Those skilled in the art can realize that this new interface architecture can be applied to any system that sends control data to a servo control machine connected to the control system.

[0039] The digital control interface and accompanying principles of the present invention are preferably applied to a machine tool controller of a machine tool that manufactures machine parts according to predetermined technical requirements. For example, the present invention provides a new paradigm that can use existing design applications such as CAD / CAM software packages and the capabilities of machine tool controllers to more directly and effectively transform CAD-generated part designs into The instructions required to correctly control the machine tool. The process of the present invention is called "direct machining".

Abstract

Method and system for a direct transmission of motion path data (310) from a generating system (204) to a control system (205) for use in controlling a servo-driven machine. For example, a machine tool for machining stock material, and the data generating system includes a computer-aided-design software package (301). Tool paths for directing the tool members of the machine tool can be extracted from a design file opened by the CAD software through the operation interface of the CAD software (302). Alternatively, the design file can be used to specify motion paths rather than end product geometry. The CAD interpreter application extracts the motion path data from the design file, eliminating the need to translate the data into another or intermediate form for controlling the machine tool.

Description

Technical field [0001] The present invention relates to the field of digitally connecting robots, machine tools, or other servo-driven machines that have systems that provide data for controlling servo-driven machines. The present invention also relates to the field of manufacturing equipment parts from appropriate materials using numerically controlled or computer-controlled machine tools. This manufacturing is based on the rough machining and / or finishing of initial material pieces according to the technical requirements of the parts to be manufactured. More specifically, the present invention relates to a new paradigm for controlling the operation of a machine tool by directly transferring processing data defining a workpiece to be manufactured from a CAD / CAM application to a machine controller. Background technique [0002] In modern industry, many machines have moving parts, which are driven by servo motors. These machines include industrial robots, coordinate measuring mach...
