Application of 3+2 CNC Machining in Mold Making Factory
Plastic injection mold manufacturers have long embraced simultaneous multiple-axis machining on machine tools with five or more axes, but more and more China injection mold makers have begun machining mold components on multiaxis platforms in the past few years, said Charlie Chan , engineering manager HS Mold & Die Co.,LTD He mentioned, however, that the common approach for machining mold parts in hous es is 3+2, or 5-axis positional machining. According to his estimate, about 8 0% to 8 75% of the multi - axis work is performed via 3+2 rather than simultaneous when cutting up to five sides of a prismatic metal workpiece in one fixturing. What is 3+2 CNC Machining 3+2 (5 axis) CNC machining , also called “positional five -axis machining” , is a technique whereby a three-axis milling program is executed with the cutting tool locked in a tilted position using the 5-axis machine’s two rotational axes, hence the name, 3+2 machining. During the machining process , ...
