Biomass tensile and shear ultimate failure stresses were measured with the aim of identifying biomass ‘‘weakest mode of failure’’ or ‘‘natural fracture point’’ as a basis for future grinder designs. Switchgrass (Panicum virgatum L.) ultimate stresses were determined for Alamo and Kanlow varieties over ranges in maturity and moisture content. Alamo had greater ultimate tensile stress than Kanlow...

Grinding processes’ stochastic nature poses a challenge in predicting the quality of resulting surfaces. Post-production measurements for form, surface roughness, and circumferential waviness are commonly performed due to infeasibility measuring all parameters during grinding operation. Therefore, it is challenging diagnose root cause deviations real-time from variations machine’s operating con...

A mini grain grinder device was created for small farms, which is used to prepare feed by grinding grains. The main working organ of the a propeller with hammer, and grains during work process depends on rotation speed hammer number revolutions propeller. Because when rotates, attached it must be sufficient crush With this in mind, theoretical studies were conducted rotations needed grind deter...

Abstract To avoid the resetting of temperature-sensitive points caused by seasonal and weather changes influence on accuracy thermal error model, a prediction compensation method for CNC machine tools without preselected was proposed based deep learning method. The original temperature data tool were converted into images directly serve as input network. improve model with 10 hidden layers cons...
