Probe has a soft touch.(Brief Article) Article from: Quality Article date: October 1, 2001 Author: Adams, Larry More results for: coordinate measuring machine cmm probe touches Measuring flexible or fragile parts with a coordinate measuring machine touch probe can be problematic because a simple touch can change the shape of the part--throwing off accuracy--or it may damage the piece upon contact. While some companies use non-contact methods to measure such parts, many companies want to reach the extreme accuracy levels that touch probes provide. However, on soft plastic, rubber, thin sheet metal or other flexible components, this may backfire. While the measurements may be repeatable, they may not always be accurate. When measured with a traditional touch probe , a flexible part may give, or change shape, upon contact before the measurement can be taken. It maybe repeatable because the force applied to the part can remain the same, but it may not be a true reflection of the part's dimension. For example, when a vinyl molded part such as a flexible vinyl cap or plug is measured with a traditional probe , the part can flex. If an operator wants to measure the position of a wire on a mechanical part, most touch probes will bend or deform the wire before a measurement can be taken. A solution is to capture the touch data as soon as possible after the
