Abstract
Abstract A longitudinally reciprocable and transversely indexable base carries parallel upright pivots, one mounting a template holder and the other a workpiece holder. The holders each have head and tail stocks to mount a template and a workpiece, respectively, shown as bladelike in nature, for pivotal movement in substantially coaxial alignment. A rotary finishing head engages the workpiece from above and a tracer engages the template from above as the latter is sustained from beneath by a reaction ball camming device. The base is reciprocated by hydraulic cylinder means, and is hydraulically indexed transversely after reciprocatory cycles. The tracer follows the contour of the template, and universal joint and connecting rod linkage means, plus the ball device, operatively articulate the template with the workpiece in such manner that the latter is gradually swung about horizontal and jogged about vertical axes as it travels horizontally beneath the finishing head to finish a compoundly curved turbine or like blade surface. The template tracer maintains the surface of the finishing head in flush, line contact with the workpiece by coaction with limit switch and hydraulic control means.
