Given a parametric plane curve \(\mathbf{p}\) and any BΓ©zier curve \(\mathbf{q}\) of degree \(n\) such that \(\mathbf{p}\) and \(q\) have contact of order \(k\) at the common end points, we use the normal vector field of \(\mathbf{p}\) to measure the distance of corresponding points of \(\mathbf{p}\
When a quadratic NURBS curve is used to describe the path of a computer-controlled cuttin9 machine, the NURBS curve is usually approximated by many straight-line segments. It is preferable to describe the cutting path as an arc spline, a tangent-continuous, piecewise curve made of circular arcs and
