RopeCAM - CNC programming of special threadsRopeCAM

RopeCAM is a standalone software specifically developed for CNC programming of so called "ropethreads", where in machining a standard lathetool or plungetool is used as opposed to using a "formtool" with the same shape as the threadprofile. These types of threads are very common in the mining industry, and are very timeconsuming to program without a efficient software for the purpose.

Support for most special thread types
RopeCAM supports both ropethreads, trapezoid threads and buttress threads with userdefineable taper/sideangle and top/bottom chamfers/radiuses. The turning routines support both roughing and finishing.

Easy to use
The threadshape is first defined in a graphical dialog. After this the increment (stepover) for the tool is defined, this controls the surface smoothness. The toolpath can then be simulated and finally the toolpath is converted to a CNC program for the CNC control of choice. The CNC program is typically a number of syncronised threadmoves (typically G32/G33). The postprocessor that creates the code can be easily modified by the user to suit any CNC machinetool.
