Touch probe system. (Suppliers Showcase: Instruments).Said to represent a new approach to coordinate measurement machine (CMM (Capability Maturity Model) A process developed by SEI in 1986 to help improve, over time, the application of an organization's supporting software technologies. ) touch probes, the Model 1015 CMM touch probe system uses a high frequency resonating res·o·nate v. res·o·nat·ed, res·o·nat·ing, res·o·nates v.intr. 1. To exhibit or produce resonance or resonant effects. 2. stylus stylus: see pen. (1) A pen-shaped instrument that is used to "draw" images or select from menus. Styli (the plural of stylus, pronounced "sty-lye") come with handheld devices that have touch screens, such as PDAs and video games. in the touch probe to detect contact with a test object. Unlike conventional mechanical switch type probes which require several grams of force to trigger, this probe will trigger on less than 10 milligrams force. This is said to allow fragile parts to be measured without damage due to stylus touch force. Also, the very low trigger force is said to improve the measurement accuracy of flexible parts. Contact is detected by measuring a change in stylus resonance resonance, in acoustics resonance, in acoustics: see vibration. resonance, in chemistry resonance, in chemistry: see chemical bond. . This change in resonance is measured by an internal sensor and electronically converted to a switch signal in the 8 mm connector. Since the stylus resonance is neither affected by CMM movement nor acceleration, false triggers are said to be minimized. (Apollo Research) Circle 104 on card |
