Great Tips from This Issue 5 TRICKS OF THE TRADE CONTENTS August 2016 Volume 19 / Number 8 00 00 00 4 MoldMaking Technology —— AUGUST 2016 Features 14 Cutting Tools: Take the Plunge: Drill vs. Mill Strategic operation planning and cutting tool system optimization make plunge roughing a productive choice for high-volume material removal. 20 Inspection/Measurement: A Case for Model-Based Definition This strategy ensures all components in the inspection value chain work together, keeping the digital thread intact from design to quality reporting. 24 Hot Runners: A Different Approach to Mold Venting New venting valves can help overcome standard mold venting limitations and improve mold performance. 30 Advanced Manufacturing: A Powerful Technology Combination Producing lightweight plastic parts with high surface quality takes the right blend of mold technology and molding process. 36 Advanced Manufacturing: Strategic Machining Combining what they know with what they have allows these makers of investment casting molds to optimize the cutting of complex contours. 42 Training/Education: Project-Based Learning University education in a shop-like setting helps mold a new generation of enterprising engineers. 46 Workforce Development: Breaking Down the Skills Gap, Part 1 You can't solve a problem without defining it first. This two-part series will help define the skills gap and offer solutions for closing it. ON THE COVER Image courtesy of Komet. This month's cover shows a very dif- ficult drilling condition for an indexable drill. The design of this particular drill, the Komet Pentron, is designed to provide excel- lent stability, chip formation and chip evacuation, and long ser- vice life, making it well-suited for plunge roughing.

So Much More When employing a model- based definition strategy, the CAD model becomes more than the nominal against which all parts are measured and inspected. PG. 20. 2. Time to Vent Venting the gases produced by the melt can reduce mold cleaning frequency and mold cavity contamination. PG. 24. 3. On the Ball Ball-filled-mold technology provides high heat transferability, constant temperature along the mold cavity and quick temperature changes, because there is less steel between the channel and part. PG. 30. 4. Get Educated To get young people interested manufacturing, their parents, counselors, teachers, coaches and others influencing career decisions must be edu- cated about financial and other benefits of choosing manufacturing as a career. PG. 46. 5. The Right Stuff The right tool management documentation platform cuts the number of people involved in a request for information and does not require an individual to wait on someone else in order to access information.
