In area efficient low error compensation multiplier design is using fixed width RPR(Reduced Precision Redundancy). We propose a new method called fixed width RPR for DSP applications. This fixed width multiplier is placed in ANT architecture to meet high speed, low power consumption and area efficiency. The fixed RPR is designed with compensation circuit for minimizing the occurrence of error. ...

Jianhao Zhang, Jinda Cai Numerical Control And Display Lab, USST, 200093 ShangHai,China Emails:[email protected] Abstract:A method of compensation is proposed based on the error model with the robot’s parameters of kinematic structure and the joint angle. Using the robot kinematics equation depending on D-H algorithm, a kinematic error model is deduced relative to the end actuator of the robot, ...

Although the five-axis machine tool presents excellent advantages of high-speed, -efficiency, and -precision machining complex curved surface parts (impeller blade), its actual motion demonstrates nonlinear principle error due to participation rotating axis. Traditional methods, such as linear interpolation, rotation center point (RTCP), optimization, can effectively control errors despite thei...

This paper presents a method of controlling serial robot for milling by an inverse kinematic controller combined with outer PD loop (Inverse Dynamics + controller), calibration and compensation errors in calculating the cutting forces. Because forces are generated at time cutting, contact area between workpiece tool, generalized differential equations motion is always variable difficult to dete...
