Cutline Studio: A Description-to-G-code Pipeline for CNC Plywood Furniture

Cutline Studio is a Windows desktop application that turns a plain-language description of a plywood project into cut-ready G-code for a 3-axis CNC router. A language model writes only a structured design specification: parts, joints and where each part sits in the finished piece. Deterministic code then builds exact part geometry, sizes every slot to the measured thickness of the user's sheet, checks the assembly in 3D, nests the parts, adds dogbone reliefs and writes G-code with true arcs. This report describes that pipeline and presents a case study on a hobby-class router running Mach3: a 3,847-move drawer job whose 86-minute run time, about twice the 37 to 45 minutes predicted by an acceleration-aware model, points to the machine-control screen's own rendering load rather than the toolpath (a confirming re-run is pending). Making the toolpath preview incremental and change-driven cut the control software's processor use from 0.53 to 0.12 of a core on the same job. Project site: cutlinecnc.com
