The classification of the Tool Path Mode. The tool path mode can be divided into 4 types: oneway feeding, reciprocating feeding, circular cutting feeding and compound feeding. The compound feeding is a mixed feed of the first three types. Oneway or reciprocating feeding are all line cutting in terms of processing strategies.
