CNC Software has expanded its Mastercam Dynamic Motion toolpaths with refined strategies for better control in specific cuts, he added. “Dynamic toolpaths are also extend- ing into other areas such as turning [Mastercam Lathe] and will continue to expand in the future. On a related note, our new radial chip thin- ning feature lets you program to a tool’s specs, delivering efficient speeds and feeds while maintaining your targeted chip thickness.” CAM requirements for toolmaking typically involve complex forms where machining is not necessarily about cycle time, noted Marc Freebrey, group marketing director, Vero Software (Cheltenham, UK). “It is how to achieve the highest possible surface quality and reduce EDM and manual finishing time,” said Freebrey. The fundamental requirements for CAM are numerous, but the most important include automatic feature recognition of complex hole and pocket features from the CAD model. “Extraction of diameters and depths from the model makes it easy to enter drilling parameters and eliminate the possibility of manual in- put errors,” he said. “Intelligent toolpaths can be created for the most complex parts with toolpaths tailored towards high-speed machining and designed to minimize the number of retracts, maintain a constant tool load, minimize any sud- den directional change and automatically smooth the CNC code.”


Multiaxis machining has become in-


creasingly common and many complex molds contain deep cavity areas and small radii that need to be machined with small-diameter tools, Freebrey said. Another big area of focus for CAM


software is the finishing side, according to Shawn Schwartz, sales and service director, Americas, for Vero Software’s WorkNC CAM software brand. “Finish- ing is such a big deal. We’re adding a


new finishing feature in the WorkNC 2016 update due out at the end of May. A major thing is the use of high-feed tooling. High-feed tooling is really the design of the tool itself, and high-speed roughing is really different.”


Supreme DC170 Visibly different, clearly leading the way.


The Ikon of a new performance class The Supreme DC170’s unique and innovative margin design ensures that the carbide’s strength is exactly where you need it;right behind the cutting edge, facing the cutting forces - precisely where greater stability significantly increases productivity. This increases the process reliability, tool life and quality – while simultaneously reducing your manufacturing costs. The Supreme DC170 – The Ikon that gives drilling a new look.
