r_g = w_gMax/t_gMax
This formula uses 3 Variables

Variables Used

Grain Aspect Ratio - Grain Aspect Ratio describes the shape of the abrasive grains embedded within the grinding wheel. It signifies efficiency of grinding wheel based on the grain's shape and fracturing behavior.
Maximum Width of Chip - (Measured in Meter) - Maximum Width of Chip is defined as the theoretical widest part a chip could have after being removed from the workpiece by a single abrasive grain on the grinding wheel.
Maximum Undeformed Chip Thickness - (Measured in Meter) - Maximum Undeformed Chip Thickness is the thickest layer of material a single abrasive grain on the grinding wheel aims to remove before it breaks the material and forms a chip.

STEP 1: Convert Input(s) to Base Unit

Maximum Width of Chip: 78 Millimeter --> 0.078 Meter (Check conversion here)
Maximum Undeformed Chip Thickness: 300 Millimeter --> 0.3 Meter (Check conversion here)

What is undeformed chip thickness?

Undeformed chip thickness refers to the thickness of the material layer being removed by each individual abrasive grain during the grinding process when there is no deformation or deflection of the workpiece material. It is a critical parameter in determining the material removal rate, surface finish, and grinding forces. Understanding and controlling undeformed chip thickness is essential for achieving desired grinding outcomes, such as precise material removal and surface quality.

How to Calculate Grain-aspect Ratio?

Grain-aspect Ratio calculator uses Grain Aspect Ratio = Maximum Width of Chip/Maximum Undeformed Chip Thickness to calculate 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 calculate Grain-aspect Ratio using this online calculator? To use this online calculator for Grain-aspect Ratio, enter Maximum Width of Chip (w_gMax) & Maximum Undeformed Chip Thickness (t_gMax) and hit the calculate button. Here is how the Grain-aspect Ratio calculation can be explained with given input values -> 0.26 = 0.078/0.3.

FAQ

What is 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 and is represented as r_g = w_gMax/t_gMax or Grain Aspect Ratio = Maximum Width of Chip/Maximum Undeformed Chip Thickness. Maximum Width of Chip is defined as the theoretical widest part a chip could have after being removed from the workpiece by a single abrasive grain on the grinding wheel & Maximum Undeformed Chip Thickness is the thickest layer of material a single abrasive grain on the grinding wheel aims to remove before it breaks the material and forms a chip.
