Some researches have studied position error of the markers how to affect attitude solving, such as Woltring et al[5] proposed an estimation method of maximum error for solving a given tracking error of the probe when markers is symmetrically distributed on the probe, Morris and Donath el at[6] extended the Woltring’s study and quantify the cumulative impact of multiple sources of error including dynamic deformation error algorithm targets and so on.
The image point of left camera coordinate system in the right coordinate system is as follows VL-R = RLT ×(AL-1×[ul vl 1]T) (5) Where, AL-1×[ul vl 1]T represents image point of markers in the left image coordinate transformating into the left camera coordinate, VL-R indicates that image points in the left camera coordinate are tanrsformating into the right camera coordinate system.

Raoet al.[2] stated that the increase of the depth of cut deteriorates the surface finish of the machined left by the carbide tool.
As M.A Elbestawiet al.,[5] stated in their research, a worn tool produces a better surface finish than a new tool (fresh tools cut well defined scallops resulting in a higher surface roughness).
Q.Liuet al.,[11] flank wear pattern produceswear lands on the side and end flanks of the account of the abrasive action of the machined surface.
