ROTARY MILLING CUTTER
摘要:
The invention relates to tools for the machining of materials by milling. The invention provides an improved form for a rotary cutting tool such as an end-mill, configured to extend tool life when increasing metal removal rates. The invention provides a rotary multi-tooth cutter (10), the cutting edge (18) of each tooth being provided along its length with a repeated waveform (20), comprising four substantially straight sections (22, 24, 26, 28) interconnected by radii (29), the first section (22) being identical with the unmodified cutting edge (18). The second section (24) adjoins the first section (22) into the tooth. The third section (26), adjoining the first section (22) on a side nearer the tool tip (16), extends at an angle (A) to the first section (22) into the tooth. The fourth section (28) is connected to the third section (26) extending into the tooth at an angle greater than the third section (26). A root radius (30) connecting the fourth section (28) to the adjoining second section (24) of the adjacent form.
