Claim 1:
2. The method for cutting a piece of material using a CNC machine coupled to a CAD/CAM system of claim 1, wherein calculating the duration of the extension move comprises calculating a smaller positive root of the quadratic equation At2+Bt+C, where t is a time for the extension move, theta is an interior angle of the corner, Amax is a maximum acceleration allowed on machine axes in a cutting plane, Fcut is a cutting feedrate, A is (1+(tan(theta/2)/2)*Amax2, B is −(2+(tan(theta/2)/2*Fcut*Amax2, and C is Fcut2.
