Basic 2-Axis Trajectory Milling

In 2-Axis trajectory milling, you specify the tool trajectory by sketching or selecting a curve that represents the final trajectory of the tool. 2-Axis Trajectory Milling Configuration • Specify a curve to represent the final tool trajectory. • Configure – Depth – Multiple Passes – Multiple Slices • Options – Datum Curve – Start …

Creating Sketched Milling Tools

Trajectory milling sequences enable you to sketch a tool. This enables you to create a user-defined tool cross-section and specify a non-standard control point for the tool. Sketched Tools • Create a sketch during tool configuration. • Tool Features – Sketch as revolved solid. – Half tool cross-section. – Right side of axis …

Understanding Trajectory Milling

Trajectory milling enables you to sweep a tool along any user-defined trajectory. You can use it for milling slots or chamfers. Trajectory Milling • Two Types – 2-Axis Trajectory Milling ♦ Select or sketch a curve. ♦ Curve must be planar. ♦ Simple to use. ♦ Automatic material removal. – 3- to …

Editing Finishing Parameters

You can use finishing sequence parameters to specify how the vertical and horizontal slicing toolpaths are created within a finishing sequence. Finishing Parameters • SLOPE_ANGLE – Divides steep and shallow areas. • FINISH_OPTION – Specifies machining method. – STRAIGHT/PROFILE/SHALLOW/COMBINED • SHALLOW_AREA_SCAN – Scanning method for shallow areas. • STEEP_CONNECT_OPTION – …

Basic Finishing

You can use finishing sequences to machine components after roughing and re-roughing. You can also use them to directly machine models containing non-solid geometry. Finishing Sequences • Reference mill windows. • Create after roughing and re-roughing. • Directly machine STL data. Cut Types • Vertical Slices • Horizontal Slices • …

Roughing Corner Options

When you rough a surface, you can add a filleting move to a sharp corner. You can also create slowdown motions before a corner and ramp up motions after a corner. Toolpath Filleting • Add a filleting move to a sharp corner • SMOOTH_SHARP_ CORNERS – NO – CONSTANT_RADIUS – …

Additional Scallop Height Control Roughing Parameters

Scallop height control enables you to generate a semi-finishing toolpath with the same tool and during the same roughing sequence. Additional Scallop Height Control • Optional extra slices • ROUGH_SCALLOP_ CONTROL – NO – DURING – DURING_BOTTOM_UP – AFTER • ROUGH_SCALLOP Figure 2 – No Scallop Height Control Additional Scallop …
