Evaluation of CNC Controllers in Milling Machines-Relationship Between Dynamic Capability, Productivity and Cost-Edición Única

Abstract

CNC controllers play a key role in the selection and configuration of a specific milling machine tool. CNC controller technologies understanding and evaluation is important in order to take reliable decisions for a required application selection or configuration. This thesis presents a structured methodology for evaluating CNC controllers in terms of dynamic capability, productivity, and a relative cost valué for different performance indexes. Performance evaluation procedures are presented to quantify different performance indexes for CNC technologies or CNC controllers characteristics based on dynamic measurements. A qualitative scheme for different machine tool taxonomies associated with each CNC technology is classified for three markets to establish a technology cost reference. Experimental results using the proposed methodology are presented for two case studies.
