virtual sensors for on-line wheel wear and part roughness

virtual sensors for on-line wheel wear and part roughness

May 19, 2014 · The ANN-based virtual sensor supports on a very simple and low-cost power meter device (that can be easily implemented in any kind of grinding machine) used as on-line input signal for the virtual sensor, avoiding thus the need for expensive force measuring devices (such as the dynamometric table) or the need for machine mechanical modification

technologies -- balancing, acoustic & vibration sensors

These processes can be monitored by sensors using ultrasonic technology (acoustic emission) that can monitor the noise emitted at the point where the part or the dresser touch the grinding wheel. The noise is usually referred to as acoustic emission signals that are elastic waves with a wide frequency range (up to 1000 kHz); generated by the energy stored and released inside the machine structure

sensors for internal grinding machines - hahn; robert s

A sensor is mounted on the grinding machine for detecting the position of the outer surface of the ring and for transmitting an electrical signal to a computer for calculating the relative OD size of the ring in comparison to a norm for rings and for controlling the transverse feed of the grinding wheel in accordance with sensed OD size of the ring

sensors automate grinding, dressing wheel positioning

sensors automate grinding, dressing wheel positioning

May 17, 2013 · By listening for slight changes in sound, acoustic emission sensors enable grinding machine owners to automate their wheel positioning and dressing processes with precision and accuracy. The SBS SB-5500-G can accept inputs from three types of sensors. From left to right are the external bolt-on sensor, the in-spindle sensor and the fluid sensor. The SBS SB-4240 external bolt-on …
