Preparing Design Models for the Mold Process

You may not be able to create a mold from a perfectly valid design model. • Design model requirements for molding typically include: – Draft on “vertical” surfaces. – Uniform thickness. – Ribs. – Ejector pin “pads.” • Preparation guidelines: – Draft applied to “vertical” faces. – Ribs should be about half …

Creating and Using Manufacturing Templates

In the process manager, you can configure manufacturing templates based on existing steps, and then use these templates to create manufacturing steps in different models. Manufacturing Templates • Based on existing NC steps. – Use in different manufacturing models. • Workcell templates. • Stored as XML files. Using Manufacturing Templates • Insert new …

Engraving on Flat and Complex Surfaces

Engraving NC sequences are generally created by the tool following a curve or a Groove cosmetic feature. The tool diameter determines the width of cut. Engraving: • Flat or Complex Surfaces • Use Cosmetic Groove or Curve features • For logos or part numbers Engraving on Flat and Complex Surfaces …

Understanding Holemaking

Holemaking enables you to create many different types of drilling cycles including standard, countersink, tapping, and reaming. Holemaking Process • Select the drill cycle type. • Select a tool. • Configure holemaking parameters. • Configure the set of holes to be machined. • Customize hole connections (optional). Figure 1 – …

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 – …

Step Depth and Tolerance Control Roughing Parameters

For roughing sequences, there are a number of parameters that control the step depth and tolerance control. Step Depth Calculations • Based on the maximum and minimum Z-heights in the mill window • MAX_STEP_DEPTH • MIN_STEP_DEPTH Figure 1 – Step Depth Calculation Step Depth Calculations Improved Tolerance Control • Tolerance …

Cut Line Surface Milling

Cut line surface milling enables you to specify the shape of the first, last, and optionally some intermediate cuts. The toolpath gradually changes the shape of the cuts according to the surface topology. Cut Line Surface Milling: • Mill surfaces using cut lines. • Toolpath gradually changes shape. • Open or closed …

Straight Cut Surface Milling

Straight cut surface milling enables you to mill the selected surfaces with a series of straight cuts. Straight Cut Surface Milling • Machine selected surfaces using straight cuts. • Machining direction: – Use CUT_ANGLE parameter. • Straddle open edges. • Avoid inner walls. • Patch slots. Figure 1 – Straight Cut …

Basic Profile Milling

Profile milling sequences enable you to machine vertical and slanted surfaces. This is useful for machining the sidewalls of pockets and for machining outside profiles of components. Profile Milling • Machine vertical or slanted surfaces. • Select or create final machining surfaces. • Continuous toolpath required. • Final cut depth determined by machined surface depth. …
