Abstract: A process for forming angled trim lines on vehicle frame cross members to mate and secure the ends of the cross members with frame side rail members with a high degree of accuracy and in a cost efficient manner. The process includes the steps of removing portions of the end of a rectangular tube to form angled trim lines and connecting the angled trim lines with the frame side rail member. A cam trimming die is used to form the angled trim lines. The die includes substantially symmetrical drivers, slide cams, and filler cams. The drivers move the slide cams and filler cams in opposing directions. The slide cams carry cutting steels that form the angled trim lines as the slide cam moves. The filler cams support the rectangular tube and produce a sheering effect with the cutting steels as they move past one another.
