Circular Interpolation –The generation of an apparently circular motion through the coordinated movements of two axes. The actual path is a series of straight line approximations generated by software algorithms. Collision Detection –The use of sensors to detect the imminent impact of two or more...

In the CNC unit, there are generally two ways of moving the tool; one is to move the tool on a straight line as shown in FIG. 3(a) illustrating linear interpolation, and the other is to move the tool on an arc as shown in FIG. 3(b) illustrating circular interpolation. In the cas...
This study proposes a design of iterative learning contouring controller (ILCC) by considering actual contour error compensation (ACEC) to enhance the contouring performance of CNC machine tool feed drive systems with linear motors. The ACEC with linear and circular interpolation is designed to ...
Hence, the proposed approach can be directly applied for a commercial CNC machine tool with linear motors currently in use without any modification of their original controllers. Both of linear and circular interpolations are verified by simulation in both air-cutting and machining condition. The ...
InterpolationBezier curvesNC machiningG(2) continuityThe G01 tool path, which consisted of linear segments, is commonly used in NC machining. There is the tangential and curvature discontinuity at the junctions of adjacent linear segments, which can cause the fluctuations of feedrate and deteriorate ...
