LNC-M520iCNC Operation2.7 Milling EASY-CAM2.7.1 PrefaceThis function provides 2D pocketing work of one allowable island. The function area has「Rough-Cutting」and「Fine-Cutting」working types. The CAM function in this controllerallows users to produce auto NC path for its pocketing of any Profile shape. It means that itcan define working piece’s geometry shape direction on the controller. Also, it will producethe corresponding post NC code after setting the related working parameters.2.7.2 Function SpecificationSince this is a CAM system that is built inside the controller. In order to get the actualbalance of the calculation efficiency of the specification, there are some using restrictionsas below:• Only allow defining one closed Profile and it is limited inside the closed Profile. Onlycan define maximum 6 islands.• The line/arch’s number of elements that are made by a single close profile and islandcannot be more than 100 sections.• Elements that are combined by Profile and Island must be closed.• Island must be surrounding by Profile. So, the island must be defined with the Profile.• Cannot have any intersect or self-intersect between islands. Also, cannot have anypoint or line connecting/cutting between islands.• For profile and island, neither can have intersection nor have connection/cuttingbetween them.• The using pocking calculation method—Horizontal Surrounding(Arachnoids).
