Delcam launches FeatureCAM 2007

Delcam's release of FeatureCAM 2007 includes enhancements to the software's automatic feature recognition functionality and to FeatureMILL's range of 3D machining strategies. The extended functionality will automatically recognize and machine complex holes for special applications. The upgraded software will enable users to specify custom hole dimensions, key geometric features, special-purpose tools and exact machining parameters. As a result, hydraulic connections, SAE ports, mold base fittings and other special holes will be automatically recognized and machined to desired specifications.

The main requirements for advanced machining are to keep the load on the cutter as consistent as possible, and so maximize its life by reducing wear, and to minimize any sudden changes in the cutting direction that will either put excessive load on the tool or require a slowing in the feed rate. The new FeatureMILL3D strategies enable users to meet both of these objectives

The new release of FeatureMILL3D will also offer Delcam's patented Race Line Machining strategy. With this option, the roughing passes are progressively smoothed out as the toolpaths move further from the main form. The resulting paths minimize any sudden changes in direction, thus allowing faster machining, with less wear on the cutter and lower stress on the machine tool.

New finishing options include a combination strategy in which 3D offset finishing is used on flatter areas and Z-level finishing used on steeper areas. The 3D offset toolpaths can be calculated with the surface stepover varying so that a constant cusp height is applied over the part. This approach will reduce the amount of hand finishing needed.

Another new strategy uses a spiral path instead of the conventional approach of machining down the job level by level. This keeps the cutter in constant contact with the job, which eliminates air moves. The smoother toolpaths also minimize any dwell marks as well as protect the cutter and machine tool
