<br />
In this work a new polishing tool of optical surfaces has been designed. We have called a porous tool, because it is formed by perforations and circular posts. The design of this new tool is based on the design of a previous petal tool which generates a desired wear. The proposed tool will be constructed in two parts; perforations are placed in the first part and posts in the second. As a first step, we obtain the function that describes the contour of the petal tool using cubic spline interpolation; from this information we determine the number of posts and perforations and their distribution on the porous tool. An iterative algorithm that solves a sequence of linear programs to find the solution of this problem is presented. Finally we show examples where we applied this method to design diferent porous tools that produce wear similar to that produced by the original petal tools, in order to make both concave and convex surfaces.
