Scientific novelty
Shaping the workpiece and forming a local metastable zone on its surface along a helical line using a local laser beam from a laser head, followed by machining with a cutting tool with a negative rake angle, which creates additional compressive deformation of the layer being cut for stable segmentation of continuous chips. Increasing tool life by reducing dynamic force loads and vibrations.
Advantages
The method involves setting the laser head to a focal length to orient the local laser beam at a 90° angle in Cartesian coordinates and a tilt in polar coordinates at an angle from 95° to 135°. This allows for the formation of a local metastable structure with variable depth on the surface of the steel workpiece. Subsequent machining of the steel workpiece with the variable metastable structure is carried out using a cutting tool with a negative rake angle in the range of -10° to -30°. The negative rake angle further creates compressive deformation for stable segmentation of continuous chips from the steel workpiece and increases tool life.
Commercial implementation
The method is intended for use at machine-building and metalworking enterprises.
