00 00 00 Great Tips from This Issue 5 TRICKS OF THE TRADE CONTENTS February 2018 Volume 21 / Number 2 4 MoldMaking Technology —— FEBRUARY 2018 Features 14 Cutting Tools Why You Need a Tool Presetter Reduce machine idle time with fast, accurate, repeatable, offline cutting tool measurements. 18 Inspection/Measurement Low-Cost Machine and Process Protection A modest investment in machine and process monitoring technology can help alleviate the expensive or catastrophic consequences of human and equipment limitations. 24 Hot Runners Hot Runner Technologies Aim to Simplify Moldmakers' Approaches Hot runner suppliers are developing solutions that remove complexities from the way that moldmakers and molders design, control and maintain their processes. 30 International Perspective Additive Manufacturing: Stand-Alone Was Yesterday Additive manufacturing is no longer considered a stand-alone technology but is being integrated increasingly into existing manufacturing processes. ON THE COVER Image courtesy of Haimer USA and Hermle Machine Co. This month's cover shows a die cast mold cavity being machined from hardened H11 tool steel at 48 Rockwell-C on a five-axis Hermle C42 vertical machining center. The finishing tool path included this 6-millimeter carbide ball-nose end mill, which was held in a Haimer Power Mini shrink fit holder running at 14,000 rpm with a 60 ipm feed rate. The more robust anti-vibration design of the Haimer tool holder combined with the rigidity and fluidity of the advanced Hermle machine tool resulted in a true mirror finish on the final product, which was machined within a tolerance of 5 microns.

Fast and Furious A fast fourier transform changes vibration data based on time values to frequency values and is useful for preventive maintenance applications because wear tends to increase both amplitude and frequency. PG. 18. 2. Scalable Solutions A range of scalable technologies enables hot runners to be supplied with simple pin-position sensing capabilities that can later be upgraded to other levels of pin control. PG. 24. 3. Laser Focused Laser sintering is useful for making sintering density changes in molding applications that require the placement of porous structures to facilitate gas venting. It also enables the production of deep features, eliminating EDM. PG. 30. 4. Data Downer When data entry and retrieval are physically difficult or cumbersome, the repair technician will avoid the task entirely or only enter a short statement about the work that was performed on the mold. PG. 36. 5. Drinking Effects Ballscrew drunkenness can lead to several negative outcomes, which includes things like machine tool inaccuracy and premature wear on ballscrews, mating nuts and guiderails.
