The mechanics of continuous chip formation in oblique cutting with single-edged tool—part II. Experimental verification of the theory
1990
Abstract Experimental results obtained during oblique cutting of annealed steel Ck 45 (SAE-AISI 1045) with a single-edged tool are presented. Extensive measurements of forces, cutting ratio, chip flow angle etc. have been carried out under a wide range of cutting conditions. The measured data obtained from these cutting tests are used to test assumptions proposed in the first part of this work. In relation to previous works dealing with oblique cutting problems the present one extends to tools with angles of tool obliquity ranging from 30° to 70° and having a large negative rake angle.
Orthogonal and Oblique Cutting Mechanics
2008
This chapter provides the engineering knowledge and modelling techniques applied in description of the material behaviour in the cutting zone resulting in chip formation and its separation from the bulk material. Geometrical and kinematical characteristics of orthogonal and oblique cutting models are classified and specified. Forces acting on the cutting tools and their measurement methods for several machining operations, such as turning, milling, drilling, boring and grooving, are presented. Moreover, forces acting in the cutting zone and their resolution on the shear plane and the rake and flank faces, along with stress distributions, are presented. The chapter highlights how components …
Modelling of Final Plastic Deformation in the Case of Continuous Straight-Edged Oblique Cutting
1992
This paper presents a complex oblique cutting model for the case of varying chip formation conditions and its practical application in relation to the results of degree of final plastic deformation in the primary shear zone is considered. A computer procedure for prediction of the shear angle is given and the place of the oblique cutting process among the results obtained previously is established.
