Linear machining parameters


Linear machining generates a tool path consisting of a set of parallel passes at a given angle with the distance between the passes defined by the Step over parameter.

With the Linear pattern strategy, SolidCAM generates a linear pattern of passes, where each pass is oriented at a direction defined with the Angle value. This machining strategy is most effective on shallow (nearly horizontal) surfaces, or steeper surfaces inclined along the passes direction. The Z-height of each point along a raster pass is the same as the Z-height of the triangulated surfaces, with adjustments made for applied wall offset and tool definition.

In the image above, the passes are oriented along the X-axis. The passes are evenly spaced on the shallow faces and on the faces inclined along the passes direction. The passes on the side faces are widely spaced; Cross linear machining can be used to finish these areas.

Angle

The Angle parameter enables you to define the angle of the passes direction. The value of this parameter is within the range of 180° to 180°. If Angle is set to , the direction of passes is parallel to the X-axis of the current Coordinate System. The order of the passes and the direction of the machining is controlled by the link settings.

The defined angle affects the step over calculation. If you are machining vertical surfaces, Linear machining works best where the angle is perpendicular to these surfaces.

Tangential extension

This option enables you to extend the passes tangentially to the model faces by a length defined by the Pass extension parameter.

When the check box is not selected, the extension passes are generated as a projection of the initial pattern (either linear or radial) on the solid model faces.

When the check box is selected, the extension passes are generated tangentially to the solid model faces.

Define Angle by

This option enables you to define the angle of the hatch passes relative to the X-axis of the current Coordinate System. The angle can be defined by entering its Value in the edit box or by picking a Line on the model.
