Dolphin CAD CAM

Dolphin Partmaster Wire EDM main features include:

• 2 Axis Parallel Profiles
• Corner Radii can be set to: Cylindrical (Standard Conic).  Conical (ISO) or by specifying the top and bottom radii (programmable)
• Tapered Profiles.  The wire angle can be changed at any point on the profile, or be changed while moving between points or around arcs.
• 4 - Axis shapes, where you can define the top and bottom contours to be machined, the final shape may be altered by specifying synchronisation points or on a span-by-span basis
• Create multiple passes for roughing and finishing with reverse direction, changes to generator setting and wire offsets (G41/G42).
• Create tag points before the end of the section to prevent the workpiece from falling.
• Create lead-in and lead-out moves – Normal, Arc and Parallel.
• Generate U and V in incremental or absolute dimensions.
• Import DXF and IGES files.
• Built in RS232 communication package with full drip feed facility.
• Graphical verification, which can show if the maximum wire angle has been exceeded, or if taper cutting the wire "overcuts".
• Specify operator instructions to be output at any point in the NC program such as tagging.
• Display the wire path in plan or isometric view points.
• Customisable post-processor or choose from the range of standards supplied which include:- Agie. Charmilles. Fanuc. Sodick. Mitsubishi. Seibu. Ona. Japax.

The information about the offset Left or Right and the number of cuts required was added in the Wire EDM module, which then creates the G codes for the target machine tool.

This simple 2 axis profile was drawn using PartMaster Cad, and then the notes were added for the Pilot and Start positions.

We can see the wire path with the taper cutting being applied and cancelled at any point around the profile, with complete control over radii settings.

The completed wire path. this whole job took about 8 minutes to get from the DXF file to the machine actually cutting.
