Comparison of two processing methods for manufacturing spur face gear master mould.

Processing mode	Processing cycle (days)	Processing cost (dollars)	Forming quality
			Machining accuracy (mm)	Machining roughness (μm)
Subtractive material manufacturing	7–10	300	0.02–0.05 mm	<0.01 μm
Additive material manufacturing	1-2	100	0.036 mm–0.181 mm	0.007–0.01 μm
