Abstract
The computer simulation method is used to test the correctness of the NURBS curve interpolation algorithm, through the comparison of the five S-phased curve acceleration and deceleration control method and the line acceleration and deceleration control method, to validate the superiority of the five S-phased curve acceleration and deceleration control method.
Highlights
At present the majority of CNC lathes only have the straight line and the circular arc interpolation functions
Because currently there has no open testing prototype in the lab, the NURBS curve interpolation algorithm and acceleration and deceleration control algorithm can not be verified through the actual parts cutting experiment, but the computer simulation can be used to analyze the efficiency and validity of the algorithm
(4) The verification of acceleration and deceleration control algorithm is accomplished by the Origin graphic visualization and data analysis software
Summary
At present the majority of CNC lathes only have the straight line and the circular arc interpolation functions. A series of head-tail connected small line segments is generated as the final cutting tool path. Because currently there has no open testing prototype in the lab, the NURBS curve interpolation algorithm and acceleration and deceleration control algorithm can not be verified through the actual parts cutting experiment, but the computer simulation can be used to analyze the efficiency and validity of the algorithm. Verifying approach (1) The simulation is conducted using software VERICUT of CNC processing simulation system. (3) After NC program generated, using VERICUT software to simulate process parts and verify the correctness of the interpolation algorithm [3.4.5]. (4) The verification of acceleration and deceleration control algorithm is accomplished by the Origin graphic visualization and data analysis software
