The process of cutting two corresponding angles in sticks or lengths of moulding. When joined together, the angles form the corner of the frame. A square or rectangular frame uses 45-degree miter cuts; frames with triangles or other shapes in the design require other angles for the miter.

Angle cuts made possible on horizontal band machines by turntables, and by head tilt on vertical cut-off machines.

A diagonal seam that joins two pieces of fabric at a corner.
