Grain-aspect Ratio Solution

Follow our step by step solution on how to calculate Grain-aspect Ratio?

FIRST Step Consider the formula

r g = \frac{w gMax}{t gMax}

Next Step Substitute values of Variables

∴

r g = \frac{78mm}{300mm}

Next Step Convert Units

∴

r g = \frac{0.078m}{0.3m}

Next Step Prepare to Evaluate

∴

r g = \frac{0.078}{0.3}

LAST Step Evaluate

∴

r g = 0.26

How to Evaluate Grain-aspect Ratio?

Grain-aspect Ratio evaluator uses Grain Aspect Ratio = Maximum Width of Chip/Maximum Undeformed Chip Thickness to evaluate the Grain Aspect Ratio, The Grain-aspect Ratio calculates the shape of the chip a grinding wheel makes. Higher ratio means wider chips and rougher finish, while lower ratio means smoother finish. By considering the desired surface finish, material removal rate, and grinding force requirements, engineers can choose a wheel with the right grain size and shape (which influences the aspect ratio) to achieve optimal grinding performance. Grain Aspect Ratio is denoted by r_g symbol.

How to evaluate Grain-aspect Ratio using this online evaluator? To use this online evaluator for Grain-aspect Ratio, enter Maximum Width of Chip (w_gMax) & Maximum Undeformed Chip Thickness (t_gMax) and hit the calculate button.

FAQs on Grain-aspect Ratio
