Basic approaches

The Basic horizontal approaches check box enables you to perform a separate lead in/lead out movement for each Z-level pass in Constant Z machining. This functionality is useful for smooth entrance into the material from outside in semi-finish machining of steep model areas.

When this check box is not selected, the tool enters the material according to the defined approach/retreat parameters, and the Z-level passes are machined successively one after the other without exits from the material.

When this check box is selected, the tool exits from the material after machining of each Z-level pass and enters again on the next Z-level pass.

• The Lead in angle parameter defines the angle between the tool approach line and the line tangent to the Z-level pass in the start point of the machining.

• The Lead out angle parameter defines the angle between the tool retreat line and the line tangent to the Z-level pass in the end point of the machining.

• The Linear extension parameter defines the length of the tool horizontal approach line.
