Mechanical probes, the earliest form of precision measurement tools, rely on direct contact for measuring and are now rarely used due to their lower precision. Trigger probes, popularized by Renishaw in the 1970s, utilize pulse signals to determine contact point coordinates, offering precise measurements. [7] [8]
Measurement accuracy and precision improved dramatically with the invention of the electronic touch trigger probe. The pioneer of this new probe device was David McMurtry who subsequently formed what is now Renishaw plc. [2] Although still a contact device, the probe had a spring-loaded steel ball (later ruby ball) stylus.
The same principle is also employed with CMM touch trigger probes (TTPs), where the machine (when used correctly) adjusts its ball-offset compensation to account for any difference between the approach vector and the surface vector.
To meet this need, McMurtry invented a touch-trigger probe device, which he then patented. The probe featured an elegant 'kinematic' location for a spring-loaded stylus, providing a highly repeatable seated position for the stylus combined with the compliance needed to measure such components. [2]
Haptic technology (also kinaesthetic communication or 3D touch) [1] [2] is technology that can create an experience of touch by applying forces, vibrations, or motions to the user. [3] These technologies can be used to create virtual objects in a computer simulation , to control virtual objects, and to enhance remote control of machines and ...
Why tourists are being told to wipe their shoes before visiting the ‘world’s clearest lake’
Tactile imaging, as a medical imaging modality, translating the sense of touch into a digital image is based on the tactile sensors. Tactile imaging closely mimics manual palpation, since the probe of the device with a pressure sensor array mounted on its face acts similar to human fingers during clinical examination, deforming soft tissue by ...
