Patterns Patterns
In this Topic Show
The Patterns page gives you control over the pattern of the cut, how that pattern is sorted, and the compensation that will be used to complete the operation.
The Pattern allows you to select how the passes are laid down.
Standard - Each
pass will be parallel to the center of rotation.
Offset - Each pass
will be an offset copy of the selected geometry trimmed to the feature
constraints.

Sorting allows you to select how the passes link to the following pass.
Standard - defines
a one-way cutting pattern with retracts between each cut.
Zig Zag - defines
a two-way or alternating cutting pattern.
Each Pattern (Standard or Offset) will be paired with a Sorting option (Standard or Zig Zag) |

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.
On without Collision Detection - the system compensates for the tool nose radius and the insert geometry without checking for collisions.

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.
