time over specific fine details of a model, without wasting time over less important, or
simpler, area. For this operation the user has to prepare a vector plt file consisting of a
frame of the same equal to the size of the model and lines over the areas be tooled. The
distance between the lines needs to correspond to the tool diameter.
•
layer –
a finishing operation in which the layers are worked on from the top to the
bottom. It gives best results for steep walls, not so much for wide area convex areas. That
is why sometimes a follow up lining operation may be required. This operation skips flat
surfaces, if the model consists of such, the surface operation may be more suitable.
•
surface
– a finishing operation for surfaces, often used to compliment the layering
operation. The algorithms qualify surfaces to be tooled based on their area in relation to
the area of the entire model. Hence small surfaces of a large model may be skipped in this
operation.
•
mixed
– a finishing operation, similar to the layer operation as it moves from top to the
bottom. However, here the tooling path is based on spirals and not layers. As opposed to
the layer operation, the mixed operation also includes the surfaces.
The choice of operations always depends on the model. The most common combination is the
roughing plus lining one.
The number and type of available parameters of an operation depend on its type.
Parameters description based on the roughing operation:
