Embodiment Construction

[0046] Referring to FIG. 1 , an NC machine tool with a conventional numerical controller NC 10 is shown. The NC 10 runs a program based on G-code, which is translated into machine tool motion by servos 36 controlled by a motion control system 32 . In this example, motion is in the x, y and z planes. In addition to the tool, the measuring probe 30 can also be mounted on the spindle 32 of the machine tool. Probe 30 is moved around workpiece 34 under program control and data 16 on the offset of stylus 38 relative to the main body of probe 30 may be transmitted to receiver 14 . This data can be used to determine workpiece size, geometry and surface finish, among other things. The program is loaded into the NC 10 using the Application Programming Interface API 18 . The API 18 is fed with programs from a software system operating in a secondary processor 20 (referred to as a "front end p.c") connected to the NC machine tool. Details of the operation of the system are contained i...

Abstract

A method for producing a measurement probe (30) inspection path on a machine tool is disclosed which includes the step of running a program e.g. a modified CAM editor program (44) which allows the selection of geometric features of a workpiece (34) to be inspected. Once selected the program will generate a measurement probe path which is included in software for loading into the numeric controller (NC) of the machine tool. The software can have cutting commands together with inspection path instructions either readable by the NC or written as unreadable instructions for use with a p.c. (20) connected to the NC controller and preferably operating at the same time as the NC.

Description

technical field [0001] The present invention relates to the control of a machine tool with a numerical controller (NC) or the like together with auxiliary software, and more particularly, but not exclusively, to the control required for measurements on the machine tool. Background technique [0002] Conventional NC machine tools make the programming of the control of machine motion relatively easy. Programs for operations such as cutting are used to control the operation of the NC machine tool. Most commonly, a program consists of commands in a low-level language, that is, it can be directly interpreted as motion control commands and other auxiliary control commands by the motion control system of the NC machine tool or other auxiliary control systems. Examples of known low-level language command sets are G-code or ISO-code. Auxiliary software (such as a program editor) can be used to assist in generating these cutting programs. For example, so-called CAD / CAM software is ...
