What is a compound angle?

In carpentry and wood processing, the compound angle consists of cutting wood at an angle to its horizontal and vertical planes. The simple cut of the mow is made at a particular angle with respect to the edge of the workpiece, while the cutting blade itself plunged into a workpiece at an angle of 90 degrees. In other words, the blade itself remains perpendicular to the wood surface, cutting between 0 and 90 degrees due to the edge of the workpiece. The new edge exposed to the cut is called chamfer. When the cut was designed to create an angle of beveling other than 90 degrees relative to the wood surface, the cut is a folded angle. Many rooms, boxes and frames are irregular-TJ. Walls or sides do not go to 90 degrees-to ensure comfortably tight joints, the ability to compose are the accurate folded joints reliably. Furniture and other accessories, such as narrowed stands and display growers, also rely strongly on compound angles. In addition, everything will be built with more than four sides or less generally require compound angles at a certain point in theirconstruction.

Cutting of a composite angle is the best performed motor or manual room saw, although many carpenters and woodworkers can produce accurate compound angles in dimensional lumber with table saws. Slices of compound angle on larger pieces may require the use of manual motorized circular saws. A motorized miter saw, also called a cutlet saw, uses a circular blade, which is thrown into the workpiece at high speed. The manual miter saw includes a specially designed guide to ensure a guide for the rear saw, SAW hand made specifically for cutting miters. The return PiS wizard is set to the angles of the skin and chamfer and ensures. Specially designed wooden or plastic miter boxes, with pre -sliced ​​slots corresponding to some favorite room angles such as 15, 22.5, 30 and 45 degrees, as well as 90 degrees are also available, but JEN rarely can be used to create a folded angle with any accuracy.

When using a folded miter saw, cutting the exact angle of the compound simply the question of calibration of the miter and bevelled angle carefully when these angles are known; Otherwise, formulas are available for calculating these angles. Cutting precise compound angles with a table saw or a hand -round saw will require the use of clamps, fences and preparations. These accessories are set according to the use of relatively complex angle formulas.
