Claim Text:
1. A method of laser-assisted machining of a bone, comprising the steps of: a) determining a target bone volume to be machined; b) calculating a temperature-dependent material properties of the target bone volume to be machined; c) scanning a focused laser beam along a surface area axis of the target bone volume at a machining rate; and d) ejecting a bone residue from the determined target bone volume creating a machined void in the bone; wherein the machining rate is determined from a laser power output, the target bone volume, a diameter of the focused laser beam, a laser scanning speed, a residence time, and a laser energy density (LED); and wherein the focused laser beam provides a narrow beam with a high power density and having low heat affected zones on the target bone volume; and wherein a governing equation for a whole geometry boundary conditions of the target bone volume is: wherein, x is an X-coordinate in a three dimensional space (m); y is a Y-coordinate in a three dimensional space (m); ρ is Density (kg/m
