SOLIDWORKS DFMXpress – Mill Rules Overview
Are your manufacturability issues bringing down your profits?
If yes, then look no further. DFMXpress, an integrated feature in SolidWorks is engineered to guide the designer on the problems faced during the manufacturing process. It automates the design process through a set of rules-based checks thereby accelerating and improving the entire design through manufacturability procedure.
In our earlier article we discussed on the drilled hole checks functionality in DFMXpress. In this, we shall explain you in detail on the Mill rules.
1. DEEP POCKETS AND SLOTS
Deep, narrow slots are difficult to machine. The long, slender end mills required to machine them are prone to chatter, which makes tighter tolerances difficult to achieve. Deep slots also make chip removal more difficult if the slot is blind.
2. INACCESSIBLE FEATURES
Features should be easily accessible for machining in the required direction. Inaccessible features require special cutters or machining techniques.
3. SHARP INTERNAL CORNERS
Sharp inside corners cannot be achieved with traditional milling and require non-traditional machining processes such as electrical discharge machining (EDM).
4. FILLETS ON OUTSIDE EDGES
For outside corners, chamfers are preferred to fillets. An outside fillet requires a form-relieved cutter and a precise setup, both of which are expensive. Blending of fillets into existing surfaces is expensive to manufacture, even with ball end mill.
