Are you having a hard time computing workpieces angles? Looking for ways to calculate angles as accurately as possible? Our experts suggest using a specific angle calculator for precise computation for smooth and precise workpiece cutting and structuring. To know more about each calculator type you can use, here is a quick guide:

What is a compound angle calculator used for?

Compound angles are the sum of two or more angles. This specific calculator is used to compute compound angle settings. It is useful in calculating workpieces’ angles when building boxes or any project that requires measurements to form a certain structure. 

Important Terms Explained

Compound

A compound cut incorporates two angles – the miter angle and the bevel angle.

Bevel

It is also referred to as blade tilt. Bevel is the tilt of the saw blade from the saw table.

Miter

The horizontal angle on a table saw is called the miter angle. It’s the same as the cross-cut angle.

miter cut

Dihedral Angle

The angle between two surface planes is what we call the dihedral angle.

Miter Joint

The miter joint joins the cut ends of two boards. 

Butt Joint

The butt joint joins the cut side of one board, also known as the cap, and the cut on the second board, also known as the butt.

Negative Angle

A negative angle is when the blade moves in the opposite direction from the positive angle. This occurs in butted joints. 

Now you know the basics, you can easily cut and form any workpieces you like. Make your calculations more accurate and build the best figure structure possible with these calculators:

Post and Board Calculator

A board with a long slope in the direction of the vertical post is rotated at a certain angle. Using the post and board calculator for the accurate computation of angles is helpful. 

N-Sided Box Calculator

An N-sided box is made from the same side pieces and bottom. To make square boxes, use the N-side box calculator to get the right angles. 

N-Sided Pyramid Calculator

You can calculate the bevel, butted and mitered joints, miter angle and complement, base and side slope, and dihedral angle.

Rectangular Pyramid Calculator

You can calculate the bevel, mitered and butted joints, miter complement and angle, side slope, and the dihedral angle.

Rectangular Frustum Calculator

For a prism-like figure, you can calculate the bevel, mitered and butted joints, miter angle and complement, side slope, and dihedral angle.

Platonic Solids Calculator

In building platonic solids, you can use this calculator to get the bevel, mitered joint, miter angle, miter complement, and dihedral angle.

General Compound Angles Calculator

In the general compound case, it should have two intersecting surface planes. Use this calculator to get the bevel, mitered and butted joints, miter angle, miter complement, and dihedral angle.

General Compound Angles (2) Calculator

You can calculate the bevel, mitered joint, butted joint, miter angle and complement, and dihedral angle. 

Flips Board on Edge Calculator

You will need to refer to other angle calculators to use this edge calculator. In simple cases, you may only need the miter and bevel angles

Kerf Calculator

You can calculate the effective top kerf and effective longitudinal kerf, which requires the bevel and miter angle. 

FAQ

How do you calculate compound angles for crown molding?

To calculate the compound angles [1for crown molding, our experts noted that you need to know the wall and spring angles. Then use the angle calculator to get the miter and the bevel cut.
