Great Tips from This Issue 5 TRICKS OF THE TRADE Contents 4 MoldMaking Technology November 2015 Features 22 Machining Jig Boring for Mold Base Accuracy Mold performance and durability depends on mold base quality, and hole making is a crucial step in the process. 26 Software Managing All That Data Product data management may have a bad rap, but making it a priority rather than an afterthought can help make the most of your design and machining information. 30 Mold Materials A New Beryllium Standard Once enacted into law, the new beryllium standard will help create jobs, ensure the continuity of future beryllium supplies and improve worker safety. 32 EDM 3S for EDM Applying the sort, set and standardize principles of 5S to EDM operations can increase efficiency by minimizing waste. 38 Liquid Silicone Rubber The LSR Learning Curve This increasingly popular thermoset material follows very different rules than any plastic. ON THE COVER Cover image courtesy of Mitsui Seiki. Mold bases feature multiple high-tolerance bores for components such as the guide pin bushings pictured here. To maximize the quality of critical bores, many shops finish them with specialized jig boring and jig milling machines. The machining tolerances for bores in mold base applications can be less than 5 microns in location, roundness, perpendicularity and straightness. Mitsui Seiki builds jig boring and jig milling machines that can last 25 years or longer, and new model features are helping to improve part quality and accuracy, and company efficiencies.

Keeping Still Thermal stability of the machine tool is a key factor in maintaining bore tolerances. When results are measured in microns, even small temperature- driven changes in machine dimensions will signifcantly affect machining accuracy. PG. 22. 2. Managing Change With a managed PDM system, engineering incorporates design changes, and when the design is approved, the engineers simply "close" the revision, which fres an automatic mechanism notifying everyone down- stream of the changes. PG. 26. 3. Break the Routine Flexible workholding systems and palletization of mold components increases productivity by avoiding the setup rituals of indicating and centering electrodes and workpieces. PG. 32. 4. Get a Little Closer The viscosity of LSR is so low that it fashes into gaps as small as 0.0002 inch, which means plates must be parallel and fat, fts and clearances are critical, and only the highest levels of precision will do. PG. 38. 5. Hand-Crafted Hand scraping to qualifed masters or gages removes surface imperfections, improving machine tool geometry. PG. 56.
