INVESTIGATION OF THE EFFECT OF DEPTH OF CUT AND CUTTING SPEED ON CUTTING FORCES DURING FACE MILLING OF STEEL WITH A RECTANGULAR CUTTING INSERT

Cutting & Tools in Technological System, 2019
У процесах механічної обробки металу бажано досягнення досить високої швидкості видалення матеріалу. Швидкість видалення матеріалу може бути збільшена до бажаного значення шляхом збільшення значення швидкості подачі, а також шляхом збільшення швидкості різання або глибини різання.

Study on Rubbing-Cutting Transition Phenomena at the Depth of Cut Increase Gradually

Journal of the Japan Society of Precision Engineering, 1968
Rubbing-cutting transition phenomena are studied on the orthogonal cutting in which depth of cut increases gradually.Specimens of steels with various hardness are cut by two dimentional tools of SKH4 that have various roundness of cutting edge. On that occasion the thrust component of cutting force falls down suddenly when a pilled-up material on the ...

Hydrogen‐Assisted Fracture of Iron‐Based Fe–Ni–Al Alloys

Advanced Engineering Materials, EarlyView.
Principal relations and fracture mechanisms of single‐phase and precipitate‐strengthened Fe–Ni–Al alloys subjected to prior electrochemical hydrogen charging are identified. The mechanisms of hydrogen effect on strength and microhardness are discussed, including hydrogen‐induced increase in microhardness and the role of hydrogen in fracture behavior ...

Numerical Simulation on Rock-breaking and Temperature Characteristics of Sawtooth PDC Cutter

Shiyou jixie
Most of the researches on bionic teeth focus on the wave tooth shape, and there are few reports on the rock-breaking properties of sawtooth cutters.Based on plasto elasticity and Drucker-Prager rock failure criteria, a finite element model of interaction

Simulation and experimental analysis of composite chamfering of superhard cutting tools based on edge grinding technology

Jin'gangshi yu moliao moju gongcheng
Objectives: Circular edge chamfering PCD turning tools often feature a chamfered surface at the cutting edge to enhance tool durability. However, the arc at the tool tip causes a large amount of chip accumulation in front of the tool, making chip ...
