摘要： A method for producing suspension parts via preforming the workpiece by roll forming. The sectional area and length of the workpiece are calculated. In the former step, more than one orthogonal cross-section is acquired from the suspension part of aluminum alloy, and the sectional area is converted into the area of a circle. An imaginary area is calculated by adding to the converted area an adequate amount of flash. In the latter step, a circular truncated cone is defined from two adjacent imaginary circles and the length of the imaginary center line between the two adjacent imaginary circles. A solid of revolution is defined by connecting these circular truncated cones, and the volume of the suspension part of aluminum alloy is substituted by the volume of the solid of revolution. The value obtained by dividing the sectional area of the workpiece by the volume is regarded as the-length of the workpiece.
