Embodiment Construction
[0034] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0035] Since the tool attitude curve is a quaternion space Q 4 The curve on , so the k-order smoothness of the tool (ie, C k , k≥1) cannot be determined by the metric on the three-dimensional vector space, but should be determined by the quaternion space Q 4 to determine the measurement above.
[0036] The method for smoothing the machining path of the five-axis machining tool in the present invention comprises the following steps:
[0037] (1) Obtain the discrete attitude vector P of the five-axis machining tool on the unit sphere i' =P i'x i+P i'y j+P i'z k and position vector, where i'=1,...
