The Chamfer Volume calculator computes the volume of a chamfer based on the inner diameter, top width, chamfer height.
INSTRUCTIONS: Choose units and enter the following:
Volume of a Chamfer (V): The calculator returns the volume in cubic millimeters (mm3). However, this can be automatically converted to compatible units via the pull-down menu.
A piston chamfer is the bevel cut into the top of the block around the piston bore. It allows the rings to be more easily inserted in the cylinder.
Some engine manuals calculate the chamfer volume differently. They take the difference of the diameters (bore and piston), multiply that difference by the circumference of the bore to create the surface area of the chamfer and then multiply that surface area by the depth of the chamfer to get twice the volume. The author disagrees with those manuals, because they are geometrically wrong (just like the piston crevice formula). Without the piston bore, the bevel is an upside-down frustum of a cone. To get the chamfer volume, you calculate the volume of that cone frustum, and then remove (subtract) the volume of the cylinder that would be in that frustum. This equation does that.
Volume is a three dimensional measurement of the amount of space taken up by an object. Volume units are cubic measurements for solid objects such as cubic inches and cubic meters. Fluids have separate volume units such as liters, fluid ounces, cups, gallons, and barrel.
The volume of an object can measured by the liquid it displaces or be calculated by measuring its dimensions and applying those dimensions to a formula describing its shape. Many such calculations are available in the following list of calculators.
In many cases, the calculators are for a column with a geometric shaped base and vertical sides. One basic formula for volume is area times a Height when the volume has vertical sides.
