An experimental research of dynamic characteristics for long wall shearer cutting unit gearbox in oblique cutting

open access: yesInternational Journal of Coal Science & Technology, 2020
Oblique cutting is a working condition in fully mechanized mining whose function is making it possible for coal shearer to cut coal wall. Coal shearer often exhibit large vibration amplitudes in oblique cutting since the shearer is forced to be bent.

Improved underwater laser cutting of thick steel plates through initial oblique cutting

open access: yesOptics & Laser Technology, 2021
Abstract In underwater laser cutting of steel plates thicker than 40 mm, the initial cutting speed was previously limited to 5–10 mm/min, because the generated melt could not be smoothly blown near the start point. Oblique cutting was considered a way to overcome this problem and speed up the initial cut.

Innovative tools for oblique cutting

open access: yesProcedia Manufacturing, 2018
Abstract Development of machining process depends of cutting tools and machine tools. Various new tools are being developed and tested. For example special tools for oblique cutting or mechatronics tools. Oblique cutting process using special tools with continued cutting edge and high value of cutting angle λs make new possibilities to research. This

An Investigation into Orthogonal and Oblique Cutting Processes [PDF]

open access: yes, 2019
The cutting process may be divided into two major types. The one type is called as straight angle cutting, where blade is in continuous contact with metal sheet from one side of edge to another side of the edge at the beginning of the cutting process. The another type is known as shearing, where the blade edge is oblique and progressively proceed from ...

Theoretical and experimental research of edge inclination angle effect on minimum uncut chip thickness in oblique cutting of C45 steel

open access: yesThe International Journal of Advanced Manufacturing Technology, 2022
The minimum uncut chip thickness (MUCT) is an important phenomenon observed both in orthogonal and oblique cutting. Rounding the cutting edge influences the initiation of the cutting process and chip formation.
