초록

A probe is a commonly used measuring device for machine tools, and its precision determines the quality of theworkpiece. The touch probe has the advantage of being small in size and easy to repair, low in price due to its simplestructure. In addition, since it has benefits such as accuracy, precision, flexibility, etc. it is widely used in variousindustrial fields(3D scanning, reverse design, positioning, etc.). However, the contact-type touch probe has structurallimitations in generating an arc by contact between the shaft contact point and the circular contact point. These arcs createcarbides and form insulating films to interfere with the contact/short circuit of the probe. In addition, a precision erroroccurs when repeated measurements are made. Since the touch probe repetition error is an essential factor affecting theworkpiece's quality and reliability, various research and development of contact materials that can reduce arc generationto improve the precision of the cutting tool origin selection touch probe are necessary to produce more precision. In thisstudy, repeated arc generation and carbide generation experiments were conducted on three types of touch probe contactmaterials (AgNi10, Ag30W70, and WC94Co6) to select a touch probe contact material with an original repetitionprecision of 0.5 m<2-sigma, Range of 3.12 m. As a result of the measurement, it was found that the contact material μ μWC94Co6 was suitable as a contact material. These results will greatly help improve the quality and reliability of varioustouch-probe contact material optimization studies and processed products.
