Embodiment Construction

[0020] Referring to the drawings, in which like reference numerals indicate like or similar parts throughout the several views, figure 1 A partial view of a portion of a four-axis B rotary table CNC machine 10 is shown. The CNC machine tool 10 has a table 12 . Base fixture 14 is mounted to table 12 and coordinate system 16 is associated with table 12 and base fixture 14 . figure 2 A top view of the base fixture 14 is shown schematically, with a coordinate system 16 shown thereon.

[0021] refer to figure 1 and 2 , the probe 18 is operatively connected to the CNC machine tool 10 . The probe 18 has a side stylus 22 and a straight stylus 20 for measuring point locations associated with the CNC machine 10 . The stylet 18 is rotatable about the central axis 54 so that the side pen 22 and the straight pen 20 can be positioned in a number of rotational positions, as described in further detail below. Ball gauge 24 is mounted to base fixture 14 for calibrating table 12 and prob...

Abstract

A method for calibrating a CNC machine comprises mounting a gauge to a table of the CNC machine and calibrating a probe to the gauge mounted on the CNC machine. A total deviation of the probe and an actual table center position from a nominal table center position for a coordinate system associated with the CNC machine are determined. A controller operatively connected to the CNC machine and the probe is programmed to compensate for the total deviation.

Description

technical field [0001] The present invention relates generally to the calibration of CNC machine tools, and more particularly to the calibration of machine tool tables and probes. Background technique [0002] Computer Numerical Control (CNC) machine tools are commonly used to manufacture items that require the use of machining processes. The coordinate system is used to program the CNC machine tool for the machining process, and the center of the coordinate system is associated with the center point of the CNC machine table. [0003] To maximize CNC machining productivity, fixtures can be used to align each part with the machine table. Fixtures allow parts with different positioning and clamping configurations to be machined at the same machine table center. When the fixture is mounted to the table, it may not be perfectly aligned, for example, due to debris or other positioning errors. [0004] To prevent installation errors due to compromised machined part quality, the...
