The Alphacam 2014 R2 Part Modeler offers programmers the ability to convert an imported DXF or DWG 2D drawing into a 3D model automatically. It works by defining the relevant views from a 2D file using intelligent loop selection or tracing around the profile of the part. Using a combination of correctly oriented profile projections, a 3D solid model can be automatically constructed, ready for manufacture.
Another R2 enhancement is a redesigned Automatic Feature Extraction dialog, with an improved layout, images for each option, and context sensitive help. Partial-hole extraction is possible by specifying a partial angle range, and small-hole chamfers can now be extracted with options on the Feature Configuration dialog to set the preferred tool directions for internal and external paths. All feature extraction commands will extract to the current workplane if possible, and the active user layer.
Clamps and Fixtures
Enhancements to the Clamps and Fixtures functions allow programmers to achieve more exact positioning and greater control against collisions, as containment and positional geometry can now be set to better position clamps and fixtures against other data. Clamp moves can now be controlled using the new “Can Pop Up” option with improved Post Processor support.
Alphacam 2014 R2 includes a number of significant enhancements to the nesting capabilities. The three major developments to this are a) Kit Nesting, wherein each part in the nest can be assigned a kit number, so that kits of parts can be nested to the same sheet; b) setting a No Nest Zone to a sheet, which will apply to all subsequent sheets; and c) the New Nesting Special Function, which prevents nesting into part apertures.
The new release also includes a new Bridged Nesting option, which will analyze the nest to determine the outer toolpath and bridge the parts together, keeping the tool down in the material while all the parts are cut out, thereby minimizing on tool lifts and re-positions.
This new functionality makes it possible to produce components that are suitable for nesting, and includes the option to create a CSV file for all processed nesting parts, which can be loaded directly from CAD into CAM.
