Application area:

This operation generates a continuous 5-axis toolpath for any spatial curves, It allows for both a single toolpath construction along a chosen curve and passes along several isoparametric lines of a selected surface, as well as conducting multi-level processing along a specified curve. It offers a wide selection of tool orientation strategies, adjustable automatically or manually by editing vectors at each point along the curve.

For the curves specified in the Job Assignment, user can modify the tool orientation vectors at each point, change the tool's movement direction along the curve, alter the machining side, compensate for the tool radius, select the interpolation method for changing the tool orientation vector from point to point, and set the stock.

Job assignment:

Edge/Curve on Surface. Job assignment is formed with the edges of the part or any curves . The tool's current orientation determines vectors at the curve points. . The tool contact point will move along the specified curve based on the curve properties and the chosen tool orientation strategy.

5D Curve. The system generates the 5-axis tool path as the projection of the arbitrary curves on the part surface. In this case the tool contact point will move in touch with the surface. The passes can be shifted from the curve by the stock or by the levels. The tool axis is located perpendicular to the surface.

Drive Faces. One can u se them for creating work passes along isoparametric lines. The isoparametric curves of the surfaces depends on its way of creation and reflect the topology of the surface. Different fillets can be machined this way very well.

Strategy:

Tool Orientation:

Controls tool axis orientation. The principal parameters of this function are the same as in the 5D Surfacing operation. See more.

Incline Shape Tool. Tilts the tool so its working side touches the machining surface during toolpath traversal.

Limit Rotation Angles:

This option specifies the limit values of the tool's angular position relative to the axes. The parameters of Limit Rotation Angles are the same as in the 5D Surfacing operation. See more.

Passes:

You can create additional work passes relative to the specified curves. The passes shifts in the direction normal to the surface. If the Flank tool orientation is selected, you can choose the direction of the shifts.

Step. Material removed in one pass between the Top and Bottom Levels. You can specify the Step both as the thickness in length units or the percent of the tool diameter as well as the passes count.

Top Level. Defines the maximal stock measured from the specified curve that must be removed by the rough passes.

Bottom Level. Defines the distance from the machined surface to the last pass. If the value is positive, the tool will follow a path outside the workpiece material at the specified distance . If the value is negative, the tool will cut the part material at the specified depth.

Z Cleanup. The function adds a new pass at the distance specified in the parameter from the Bottom Level.

Direction. With the Flank tool orientation strategy active, you can select the direction for laying out rough passes.

Along Surface Normal. The layout of passes follows the direction normal to the surface.

Along Tool Axis. The layout of passes follows the vector of tool axis.

Corners smoothing:

When there is a sudden change of the tool direction, the milling control performs deceleration before starting the turn, and then accelerates again. This fact can lead to vibrations and high tool and milling machine wear. The problem can be solved if the toolpath has very few or no breaks. For this reason, in the system there is the toolpath smoothing function using the defined radius for machining inner or outer corners of the model. The principal parameters of this function are the same as in the 2D Contouring operation. See more.

Continous axial shifting:

With the Flank tool orientation strategy is in use, you can create a toolpath with smooth changes in the tool's axial displacement along the path relative to the specified curve.

Start Shift Value. It is t he tool's axial displacement at the start of the toolpath.

End Shift Value. It is t he tool's axial displacement at the end of the toolpath.

Sorting:

Controls the sequence of toolpath passes during the surface machining .

Toolpath uniting mode. Controls the order of pass execution in the multi-pass machining of different profiles on the part. Parameters of this feature are the same as in the 2D Contouring operation. See more.

Idling minimization. The order of the profiles machining is sorted to minimize the idle motions. Parameters of this feature are the same as in the 2D Contouring operation . See more.

Milling type. Сan be assigned in almost all operations, except for the curve machining operations. This allows the user to control the required milling type (climb or conventional) during the toolpath calculation process. The parameters of the Milling Type are the same as in the Waterline Roughing operation . See more.

Project toolpath onto the part with offset:

Determines the method of toolpath creation relative to the surface of the part. Parameters of this feature are the same as in the Startegy tab, in the Transformations item of the 2D Contouring operation . See more.

Trimming:

Allows for the skipping of surfaces not intended for machining and allows for the extension of the toolpath . The parameters of Trimming are the same as in the Waterline Roughing operation . See more.

Transformations:

Parameter's kit of operation, which allow to execute converting of coordinates for calculated within operation the trajectory of the tool. See more
