Introduction

Tathagata Chakraborty is an inventor based in Pune, India. His patent work addresses the computation of toolpaths for machining pockets, with a focus on planning tool movement and cutting operations.

Latest Patents

Chakraborty is associated with 1 patent: “Method and System for Computing Toolpaths for Machining Pockets.” The invention describes a method and system for machining a pocket in a raw material body. It uses a two-dimensional pixel representation of the machining tool and pocket cross-section to determine a starting point and calculate successive toolpath segments.

For each potential tool movement, the method evaluates tool engagement and selects a move based on the required engagement value or the pocket boundary. It then distinguishes cutting from non-cutting sections, identifies trochoidal and boundary region groups, and connects curvilinear cutting sections with link moves to form a trochoidal toolpath. The process uses the raw toolpath to compute the complete toolpath.

Career Highlights

Chakraborty works at HCL Technologies Limited. His patent reflects an engineering contribution to computer-assisted machining, particularly the planning of tool movement when machining pockets.
