A RESEARCH ON APPLICATION OF MULTI-AXIS INTERPOLATION METHOD IN POSITION-BASED MOTION CONTROL

Abstract

Controlling mechanisms in an accuracy system has been investigated in many recent studies. The coordination of synchronous movements of many mechanisms in a system, called ‘Motion Control’. This coordination creates a system that moves smoothly with high speed and precision. Current control systems use complex and high-cost equipment. In this study, a simple solution for precise position control is presented, applying interpolation methods on the JXC73 multi-axis cylinder set. The PLC programming controller connected to the JXC73 controls the electric cylinders by linear interpolation and circular interpolation to accurately put the product into different positions. Experimental results show that with shaft speeds below 100 mm/s, complete accuracy is achieved. When the speed increases higher, there will be some misalignment cases. In addition, the SCADA interface is used to make controlling and monitoring the model easier. Using the JXC73 multi-axis controller simplifies the coordinated control of motion axes without increasing errors, helping to reduce equipment usage costs.
