Rough machining parameters

• Smooth

At the end of every pass, the tool continues moving along the geometry until it meets the previous pass; then it retreats from the material. A smooth material boundary results from this type of turning.

• Stairs

At the end of every pass, the tool retreats away from the material. A stairs-shaped material boundary results from this type of turning.

• Ramping

Machining is performed in a zigzag manner: each odd cut is performed at an angle to the Z-axis; each even cut is performed parallel to the Z-axis. In such manner, the point of contact between the tool and material is changing, preventing wear of tool's cutting edge.

• Zigzag from middle

This option enables the tool to approach the geometry in the middle point. From this point, the tool moves to the geometry in both directions: first, all machining cuts are performed in one direction, then in the other direction.

This parameter enables you to define the distance between each two successive roughing passes.

Equal steps- The distance between two successive cutting passes is defined by the Equal steps.

Adaptive Step down- In areas where the horizontal distance between the passes is significant, Adaptive Step down can be used to insert extra passes and reduce the horizontal distance.

This parameter enables you to define the distance to which the tool retracts after each cutting pass. The retract movement is performed along the Z-axis over the cutting level. Then the tool moves parallel to the X-axis to the start point of the next cutting pass; the movement is performed in the Rapid mode. Then the tool descends along the Z-axis to the next cutting level and continues the machining.

• One way

The tool path passes are performed only in the direction of the geometry; the tool returns to the starting point of the next pass in the Rapid mode (G0) outside of the material.

• Zigzag

This option enables the tool to cut the material with both cutting edges. The tool performs forward and backward passes along the machining geometry.

This option enables you to perform rough turning at an angle to the Z-axis. Such capability enables you to optimize the cutting passes for machining of inclined revolution faces of conical shape.

Step over

This parameter defines the sideways distance between each two successive groove-cut steps; this distance should be smaller than the tool width.

• Side to side

Cutting passes are performed in the direction defined by the geometry (taking into account the geometry modification).

• From middle outside

Cutting passes are performed from the middle of the cutting area outwards first in one direction, than in the other.
