Machining Deflection Solutions

Workpiece material：S15C(HS20)	Parts diagram
Processing machinery: Dragon gate (paddle) milling machine
Tools：PD1006R（X407）
Conditions: rotation speed 315r/min Cutting speed 150m/min Feed rate 0.2mm/r Cutting depth 1mm

Results: P10 blade, but due to the cutting heat deformation, and finally had to re-processing. Later installed X407 blade PD1006R, reduce heat, there is no need to re-processing.

Summary: heat generated in the cutting, 60% -70% flows to the swarf, 20% -30% flows to the cutting edge, the rest flows to the workpiece material (the less heat, sometimes flows to air). If the heat flow to the cutting edge, i.e. the cutting edge wear, the cutting resistance increases, so, heat is regenerated when the rise in the temperature of the whole of the cutting edge, the friction between the workpiece material and the cutting edge becomes large, the workpiece material would be the effect of heat stress. Sheet is because of such heat and deformed. To use a material that can withstand the temperature rise, such as containing a large amount of titanium carbide blade, but also consider how to make the chip discharge performance is better.
