Dynamic Rounding Stability in Through-Feed Centerless Grinding

Ultrasonic assisted creep feed grinding of Inconel

The paper details the effects of depth of cut and vibration amplitude when ultrasonic assisted (US) creep feed grinding Inconel 718 with an open structured alumina based wheel. The workpiece was actuated at a constant frequency (~20.5kHz) via a block sonotrode attached to a 1kW piezoelectric transducer-generator system. A full factorial experimental array comprising 12 tests was conducted invol...

Teeth Grinding: Is Emotional Stability related to Bruxism?

This study examines the association between personality traits and bruxism, the repetitive grinding or clenching of teeth. Community-dwelling participants (N = 470) had a comprehensive oral examination by a dentist and completed a dental history and personality questionnaires. Consistent with the literature on state anxiety and depression as antecedents of bruxism, Neuroticism-related traits we...

Assessment of Dynamic Stability During Walking in Below-knee Amputation

Purpose: Dynamic stability reduces in patients with unilateral amputation; so, it is important to recognize changes in balance during walking. This study aimed to investigate the dynamic stability of unilateral below-knee amputation during walking. Methods: The present study was a quasi-experimental study, in which 10 patients with knee amputation and 10 healthy young people participated. The ...
