This invention relates to the field of profile processing technology, specifically disclosing a method for cutting profiles. The method includes the following steps: determining the lengths of each side of the profile's cross-section; summing the lengths of all parallel sides to obtain the total length, defining them sequentially as a first group and a second group according to their total length; randomly selecting one side from the first group as the first side, and randomly selecting one side from the second group as the second side; determining the angle between the first and second sides as α; passing the profile through the fixed blade's fixed edge and the moving blade's moving edge; setting the first side parallel to the horizontal plane, and moving the moving blade relative to the fixed blade along a first direction to complete the cutting of the profile, wherein the angle between the first direction and the horizontal plane is half α. This method avoids deformation of the first and second sides, prevents burrs caused by deformation, avoids secondary shaping, saves costs, and helps ensure the strength and other properties of the profile.
