This invention relates to improvements in milling machines and has particular reference to an improved structure for the production of varying or irregular surfaces or contours.One of the principal objects of the present invention is the provision of an improved automatic machine particularly adapted for the production of long work pieces, such as airplane spars or the like having variable height and twisted or warped effect final surface contours. A further object of the invention is the provision of an improved type of milling machine facilitating the continuous control of both depth and angle of cut being produced. An additional object of the invention is the provision of a machine of this character in which the cross movement may be correspondingly simultaneously varied so that the cutter will accurately describe a sinuous or other path along the surface being formed on the work piece and in which the several movements may be automatically controlled in a simple and effective manner. The invention further contemplates an improved type of milling machine in which the angular relationship between the cutter and work may be varied and in which means are provided effective to compensate for potential displacement of the cutter with respect to the traverse path resulting from such angular adjustment.
