METHOD OF DETERMINING FACE ANGLE IN END SECTION OF END CUTTERS Russian patent published in 2014 - IPC G01B11/26 

FIELD: physics.

SUBSTANCE: method involves fixing a rectilinear elastic strip on the front surface of a tooth of a cutter 2 in its end section at a distance L from the end of the cutter 2, said strip enabling extension of the surface of the face angle for visual perception thereof. The cutter is placed orthogonal to the plane of a microscope table 1 so that the sighting line of the eyepiece passes through the vertex of the tooth on the end of the cutter and the longitudinal axis of the cutter. The microscope lens 3 is moved in the vertical plane towards the cutter by a distance L. The microscope table 1 or eyepiece is turned until the sighting line is superimposed with the longitudinal face of the strip. The turning angle of the microscope table or eyepiece θ is determined and the face angle γ is then determined from a given relationship.

EFFECT: easier measurement of the face angle, enabling measurement of the face angle γ of a cutter with diameter greater than 3 mm or with any number of teeth, including less than three, using a toolmakers' microscope.
