Select this box to increase the speed of the tool when it changes from one tool motion to the next in the 3 Axis Planar and Rest Material > Planar operations.
This box is active only when the Leadin Move and the Leadout Move are both set to the None option.
The tool speed decreases when the tool must go from one linear move to a non-tangent move. SURFCAM puts several more linear moves between two non-tangent tool moves in 3 Axis high speed machining. SURFCAM uses a tangent arc between the non-tangent tool moves when it designs the linear moves. When the design is completed, the linear moves replace the tangent arc. These linear moves increase the tool speed.
Threshold Angle
SURFCAM calculates when to put several linear moves between two other linear moves by looking at the angle between them. If that angle is greater than the Threshold Angle parameter, the linear moves are put between the two tool moves.
Max Error
SURFCAM uses the Max Error parameter to calculate how many linear moves are needed and their length. SURFCAM calculates the size of an arc between two non-tangent moves by looking at the intersection of the two moves. The distance between the midpoint of the arc and the two lines intersection point must be smaller than the Max Error parameter. The number and size of linear moves is calculated from this arc.
