Adaptive Error Control Algorithm for High Speed Two-Axis CNC Contouring …

WebDec 1, 2012 · Fig. 1. Typical structure of cross-coupled control. In conventional variable-gain CCC, Cx and Cy can be derived easily. For a linear contour, these are given by (2) C x = sin θ, C y = cos θ where θ is the angle of the linear contour with respect to the X -axis. For a circular contour, (3) C x = sin θ − E x 2 R, C y = cos θ + E y 2 R ... WebJun 1, 2015 · The reason behind that may lie that the contour errors at quadrant transitions were also affected by other uncertain factors, e.g. static friction. To ascertain this, further studies are required. ... Dynamic errors in type 1 contouring systems. IEEE Trans. Ind. Appl., 4 (1972), pp. 477-484. View in Scopus Google Scholar [5] each branch

Proc IMechE, Part B: J Engineering Manufacture 2016; 230(11): 2036–2046. WebFeb 1, 2015 · The contour control effort contribution was determined by the line passing through the tangential circle center and the actual point. This model can be written as a linear combination of tracking errors plus a curvature-related item. The CCC was in position loop and the stability was analyzed via small gain theory. WebDynamic Errors in Type 1 Contouring Systems Abstract: The general nature of contouring errors experienced in type 1 servo systems as a result of command contours is described.
