Hierarchy of parameters influencing cutting performance

2017-3-22  performance. Cutting performance is generally evaluated by various parameters such as, production, specific en-ergy, chip size of cut material, cutting force, pick wear, pick consumption, etc. The present study describes an approach to identify critical parameters that affect the performance of surface miner (SM) based on field data

Hierarchy of parameters influencing cutting

Abstract. Applicability of a surface miner (SM) must be based on a careful assessment of intact rock and rock mass properties. A detailed literature review was made to identify different parameters influencing the performance of various types of cutting machines deployed in different parts of the world.
