Real-time PH-based interpolation algorithm for high speed CNC machining
Various methods for parametric interpolation of
non-uniform rational B-spline (NURBS) curves have been
proposed in the past. However, the errors caused by the
approximate nature of the NURBS interpolator ...
Development of a Pythagorean-hodograph interpolator for high speed CNC machining
Methodologies for parametric interpolation for NURBS curves have been proposed in the past.
However, the errors caused by the approximate nature of the NURBS interpolator were often
neglected. This paper ...
Sharp Corner PH Interpolation Algorithm for High Speed CNC Machining
Various methods for parametric interpolation of NURBS curves have been
proposed in the past. However, the errors caused by the approximate nature of the
NURBS interpolator were rarely taken into account. This ...
LOOK-AHEAD NURBS-PH INTERPOLATION FOR HIGH SPEED CNC MACHINING
Various methods for parametric interpolation of NURBS
curves have been proposed in the past. However, the errors

On modeling tool performance while machining aluminum-based metal matrix composites
Tool performance while machining aluminum-based metal matrix composites has been investigated by developing finite element models based on particle size and volume fraction of the workpiece. Two types of finite element ...
میان یاب های پیش نگر NURBS-PH برای فرزکاری سریع در کنترل عددی
روش های مختلف برای میان یابی پارامتری بر روی منحنی های NURBS(Non-uniform Rational B-spline) در گذشته پیشنهاد شده اند. اما در این روش ها، خطاهای ناشی از ماهیت تقریبی میان یاب NURBS معمولا در نظر گرفته نمی شوند. در این ...
