Roughing is the first stage of machining. This strategy is used to remove large volumes of excess material very quickly and leave a small amount of stock for semi-finishing and finishing strategies. You can use this strategy to create a rough component from a rectangular or core-shaped block.

Toolpath cuts material in successive Z-levels, working from top to down. The 'Depth step' parameter defines the distance between two Z levels. Toolpath is created from model slices and offset outwards. The distance between two offsets is defined by step-over. The toolpath segments are trimmed to block limits. The result is a rough component with a staircase effect over the whole component, which differs from the finished component by a thickness whose value is defined in the offset field.

Note: If no stock model is defined, then the part must have a closed pocket. Otherwise, no toolpath can be generated.

Note: If the part has open pockets or is an open geometry in general, then a stock must be defined or a 2d containment must be defined.
