sensors | free full-text | virtual sensors for on-line

Grinding is an advanced machining process for the manufacturing of valuable complex and accurate parts for high added value sectors such as aerospace, wind generation, etc. Due to the extremely severe conditions inside grinding machines, critical process variables such as part surface finish or grinding wheel wear cannot be easily and cheaply measured on-line. In this paper a virtual sensor

suitability of integrated sensors for the determination of

Feb 01, 2019 · Hence, this paper explores the qualification of sensors integrated into the grinding machine for extracting the aforementioned information with high accuracy of phase. For this purpose, two acceleration sensors mounted on the workpiece spindle and the tailstock, an acoustic emission (AE) sensor applied to the grinding wheel, and the motor current of the directly driven headstock spindle are …

control engineering | acoustic emission sensing helps

Apr 14, 2015 · The acoustic sensor monitors the high-frequency vibration of the dressing wheel as it contacts the grinding wheel and "listens" for the sound of the two coming together. The sensitive instrument requires only a small number of grains of the wheels to make contact to indicate a touch. Wheel shape confirmation

tooth grinding - possible causes & what you can do - ark

Jan 22, 2013 · While many kids outgrow grinding their teeth, intervention may be necessary if they don't. Tooth grinding over a prolonged period (especially with permanent teeth) may put them at risk for worn-down teeth, tooth sensitivity, jaw pain, headaches, etc. There is no one accepted reason as to why it happens, but there are several factors that may be contributing to the problem:

what is biofeedback and how does it treat teeth grinding

For teeth grinding, the sensors are attached to the face and jaw. They monitor activity in these areas and use flashing lights or sound to indicate when there is stress. These auditory and visual cues help the person with this disorder recognize when stress occurs, and then learn better and more appropriate ways to …
