Problems solved by technology

Obtaining accurate data of the blunt edge circle is a prerequisite for using a micro-milling cutter. Since the blunt edge circle of the micro-milling cutter is very small, and most of the cutting edge materials are polycrystalline or polycrystalline diamond materials, most of the existing technologies use non-contact measurement method, its measurement accuracy is low, it cannot meet the needs of actual use, and some even cannot be measured at all

Abstract

The invention discloses a micro-milling-cutter cutting edge blunt circle measurement device, and belongs to the technical field of subtle measurement. The device comprises a CCD microscope mechanism, a measurement platform, a micro-milling-cutter clamping mechanism and a contact-type roughmeter. The measurement platform is arranged on a base below the CCD microscope mechanism, and the micro-milling-cutter clamping mechanism is arranged on one side of the measurement platform. The device is simple in structure and convenient to use, and greatly improves measurement efficiency. The invention further discloses a micro-milling-cutter cutting edge blunt circle measurement method, a micro-milling-cutter cutting edge overlaps with a narrow seam to form an inverted-V-shaped micro-protrusion, a probe of the surface roughmeter slides in the radial direction of a micro-milling-cutter to measure a surface profile, and data are input into a computer to obtain a cutter cutting edge blunt circle. According to the measurement method, the measurement precision is high, the measurement speed is high, and the measurement method is suitable for being used for efficiently and quickly measuring the micro-milling-cutter.

Description
