Patterns Patterns
In this Topic Show
The Patterns page gives you control over the pattern of the cut, and the compensation that will be used to complete the operation.
Force Down Cutting - selecting
this option will force the finish to be cut from each side of the groove
one at a time, each in a downward direction, to the middle of the groove.
Adding an overlap will set each pass to go past the center of the groove
half the specified amount.
Overlap - sets the total distance between the two passes exits, not including any leads that are uses.

Basic Finish - breaks the finishing
pass into separate groups defined by either vertical faces, turned diameters,
or a combination of the two.
Each tool has a theoretical point placed on it as seen in red in the animation below. In the case of tools with a radius of any size, this point is not actually on the tool, but on the horizontal and vertical intersections of the radius. It is this point that the toolpath plots out. When compensation is used, it is designed to place the actual tool and not just its theoretical point on the geometry. This can be accomplished with System Compensation, Machine Compensation, or a combination of the two.
System Compensation
This
specifies whether or not the system compensates for the insert geometry
and the tool nose radius.
Off - the selected geometry is used as the program path; Machine Compensation should be used.
On with Collision Detection - the system compensates for the tool nose radius and the insert geometry and avoids any detected collisions.

System Compensation: Off |

Machine Compensation
Outputs the necessary codes to allow
for the user to enter compensation data at the machine. When this
is done, the machine will alter the path based on the data entered
at the machine. This can even be used in combination with System Compensation
in order to compensate for tool wear or other unforeseen variables.
Off - no compensation commands are output in the posted program.
Comp Left / G41 - outputs the left compensation command in the posted program.
Comp Right / G42 - outputs the right compensation command in the posted program.
