Hints and Tips: Cleanup
Cutters Usage
Legacy Cleanup supports any tool combination of Ball nose, Bull nose and Flat end, for the previous and current tools. To reduce air cutting, keep the flat portion of the current tool as close as possible to the flat portion of the previous tool.
In Legacy Cleanup, do not use a Conic tool as the current tool.
In Cleanup, do not use a Conic tool as the current tool or as a previous tool.
In Cleanup, the flat area of the current tool must be the same as the flat area of the previous tool. Therefore, if the previous tool is a Ball tool, the current tool must also be a Ball tool. If the previous tool is a Bull Nose tool, the current tool must be either a Flat tool (with the same flat area as the previous Bull Nose tool) or a Bull Nose tool also with the same flat area as the previous tool.
Deep Cavities
Deep cavities should not be milled using Cleanup. Some users may find the use of "along contours - all areas on surf" (with or without multi layers in horizontal) satisfactory for limited needs. Our recommendation is to prefer Volume Milling 3D With Stock for reroughing.
Importance of User Contours
It is recommended to define User Contours that are away from the milling zones (more than [previous tool diameter + 2*previous tool offset] from the corner). User Contours that cut the milling zone may, in very rare cases, cause treatment of horizontal portions as vertical. If the User Contours are near the milling zone, this may cause unmachined areas.
Down Step
The down step is used not only for machining but also for splitting between horizontal and vertical areas. For example, having a 2 mm stair in a tool path using Down Step = 3mm, will not create a vertical milling zone. But if you defined Down Step = 0.5mm, the same place is milled using vertical strategy. For this reason, when milling "Only Horiz. On Surf.", the down step parameter is displayed. If you want to mill the horizontal and vertical areas in two separate procedures and receive good coverage, the down step should be unchanged.
Please note that defining a very small value for Down Step, increases the calculation time.
