SELECTION OF EFFICIENT CUT PATTERN FOR SIMPLE POCKET MACHINING IN TRADITIONAL MILLING
Keywords:
Cut Pattern, Direction Parallel Path, Contour Parallel Path, Tool Path LengthAbstract
Product quality and process efficiency are the two major factors in competitive manufacturing. Currently, most of the milling operations in die and mold manufacturing are based on experienced-based approaches, which need a lot of time and effort. To reduce the time and effort needed in the traditional approaches, cutting parameters should be selected on a scientific basis. In mold and die manufacturing, estimation of the machining time of tool paths is a pre-requisite for planning the machining process. Mainly two types of cut patterns can be observed in end milling operation: direction parallel and contour parallel. Each of these types of cut patterns has its own benefits and limitations. Besides, the machining time is different for each of these cut patterns. In this work, models for different tool path patterns have been developed to calculate machining time. Different cut patterns were then compared based on the calculated machining time. The developed models were later validated by experimental results.
