Fax This DocumentSuggested Technique for Creating a 4-5 Axis Trajectory Mill Sequence.
Procedure
- To begin creation of the tool
path, a 4-5 Axis Workcell must be previously defined and activated for
the Operation. The type of NC sequence must be chosen by selecting
Machining, NC Sequence, New Sequence, Trajectory, 4 or 5 Axis, Done.
This presents the NC SEQUENCE and SEQ SETUP menus which contain all the
options necessary to define the NC sequence.
Figure 1
- Define or retrieve a tool
appropriate to create the trajectory tool path using the new Tool
Setup option if a tool has not been previously defined or if the
tool used in the previous NC sequence is not correct for the trajectory
sequence. Select an appropriate coordinate system and retract plane
using the Coord Sys and Retract options respectively, if
they have not been previously established.
- The CUSTOMIZE dialog box
is displayed with an Automatic Cutmotion set as the default.
Select Insert and the CUT MOTION SETUP menu is displayed.
See Figure 2
Figure 2
- Check the necessary options in
the CUTMOTION SETUP menu to define the sequence. Select
Done. Select or create a mill surface and select which side of
the surface to machine. From the SELECT SRFS menu select which
surfaces to machine. In a 4-axis sequence the the surface for the tool
to follow will have to be defined. From the CUT MTN menu specify
the cut motion depth. The FROM/TO CONTROL and AXIS CONTROL
options can be defined at this time but in this example they will
defined in the next step. See Figure 3.
Figure 3
- From the CUT MTN menu
specify the cut motion depth. The FROM/TO CONTROL and AXIS
CONTROL options can be defined at this time but in this example they
will defined in the next step. See Figure 4a and 4b.

- After the toolpath has been
displayed the FOLLOW CUT dialog box is displayed. The CUT
OPTION can be redefined if necessary. Select OK from the
FOLLOW CUT dialog box and OKfrom the CUSTOMIZE
dialog box. See Figure 5a and 5b.

- The completed tool path can be
viewed by selecting Play Path.
