Great Tips from This Issue 5 TRICKS OF THE TRADE Contents 4 MoldMaking Technology May 2015 Features 28 Software Design Right the First Time Simulation of both the induction heating and injection molding processes optimizes cycle time and final part results. 32 Software The Misunderstood Cutter Path Normal vectors are not always the best choice for milling complex mold surfaces. 38 Mold Material/Surface Treatment Expanding Aluminum's Potential Hard-coating provides a number of benefits that make aluminum tooling an attractive alternative to steel. 44 Machining Making the Complex Simple Tool center point management streamlines five-axis programming and setup. ON THE COVER This month's cover is a rendering of a tablet housing and its cavity and core inserts. It highlights the induction heating elements run- ning into the tool and a temperature plot taken during the injection phase of the process that shows that only the surface of the mold touching the part is hot. The rest of the mold remains relatively cool. See related story on page 28. Cover image courtesy of Autodesk.

Sum of All Benefts Some of today's integrated CAD functionalities reduce data redundancy to a mini- mum, retain all necessary specifcations and quickly adapt geometries after import. PG. 16. 2. Powerful Duo The two most important things to review when evaluating an induction heating system are that heating is occurring in the proper locations on the mold and that the surface is being heated to the desired temperature. PG. 28. 3. Be Specifc One mold-specifc CAM feature is a semi-automated method that uses a specifc milling algorithm to analyze the part, avoid collisions and look ahead to smooth out transitions in the calculated cutter paths. PG. 32. 4. Time to Get Tough Nickel boron hard-coating is often used on aluminum molds with complex geometries or minimal draft allowances that interfere with part release, such as deep ribs or thin- wall conditions. PG. 38. 5. Get to the Point Tool center point manage- ment, or rotary tool center point, simplifes fve-axis programming and setup complexity. It makes the program and the part setup independent from machine setup and confguration. PG. 44.
