Abstract

A cutting tool for a milling machine, for instance, can be accurately aligned in a fixture by focusing a light beam onto a cutting plane of the tool. Accurate positioning is accomplished by adjusting the fixture using the tool center as the center of rotation.

Turning Tool Alignment System

A cutting tool for a milling machine, for instance, can be accurately aligned in a fixture by focusing a light beam onto a cutting plane of the tool. Accurate positioning is accomplished by adjusting the fixture using the tool center as the center of rotation.

The fixture as shown in Fig. 1 includes a first optical means shown as an autocollimator 1 to adjust the top surface of the tool for horizontal flatness, a second optical means shown as a laser beam generator 2 and a position sensitive photocell 3 for adjusting the cutting plane of the tool, and an adjustable plate 4 for performing the alignment adjustment according to the optical means. A base plate 5 is provided for supporting the adjusting plate 4.

In operation, the cutting tool is placed into a tool holder 6 and adjusted for horizontal flatness by viewing the autocollimator 1.

The autocollimator 1 measures the flatness by reflecting a vertical light beam 7 from the top surface of the tool. Either a cross hair viewer or a position sensing photocell is used to sense the reflected light beam for true vertical. The tool is adjusted within the holder 6 until the reflected beam is within true vertical tolerance.

The laser beam 8 is directed to a cutting plane 9 of the tool to be positioned, and the differential screw 10 (Fig. 2) is adjusted until the reflected beam is precisely positioned on the position sensitive photocell 3, as determined by a readout means, not shown, which se...
