Suggested Technique for Creating a 4-5 Axis Trajectory Mill Sequence.


This Suggested Technique describes a method for creating a 4-5 Axis Trajectory Sequence and Previewing the Axis Definition using the Axis Control functionality.
Procedure
  1. 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.

  2. 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.
  3. 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

  4. 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.

  5. 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.

  6. 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.
