Embodiment Construction
[0062] The method of the present invention will be described in further detail below in conjunction with the accompanying drawings.
[0063] Such as image 3 As shown, the present invention is applicable to the command point shaping compression interpolation method of the numerical control device, comprising the following steps:
[0064] Recognition of continuous micro-segment processing area: According to the read-in NC processing program, judge whether any three adjacent instruction points on the surface to be processed meet the continuous processing conditions;
[0065] Estimation of interpolation points: When any three adjacent instruction points on the surface to be processed meet the continuous processing conditions, through the middle point of each adjacent three instruction points, the distance between the interpolation and the middle point is set for the tolerance of the numerical control device and is consistent with the For arcs with tangent line segments between a...
