In this paper, the methods of structural – parametric synthesis of a parallel manipulator PM with two sliders, which can be used in a cold-stamping processing technological line for feeding and stamping the wakpieces, are described. A PM with two sliders is reinforced tirined by connecting two sliders (input and output objects) using one passive and one negative closing kinematic chaine circuits (CKC). The passive CKC does not impose a geometric constraint connection on the movement of the sliders and the geometric parameters of its links are varied vary.
Keywords: parallel manipulator structural-parametric synthesis, Chebyshev and quadratic approximations.
