Common Cuts in Vintech RCAM v5

In December 2009 Vintech expanded the CAD/CAM system Vintech RCAM-Pro v5 with the final version of the functions for creation of common cuts.

The functions for common cut allow machine time reduction for processing by program with 10 to 15% on the average and decrease metal scrap.

Normally, the creation of common cuts requires experience and qualification to solve the following problems:

• to nest the parts for common cut – on a distance one cutting diameter,
• to build cutting paths, according to the optimal sequence of the common parts walking,
• to build lead ins/lead outs of the paths.

The using of common cuts has some "natural" known restrictions: roughness of the one side of the cut during plasma cutting, inapplicability of the methods for none-equidistant programming.

Until now, in the versions of the system Vintech RCAM, were developed the following methods for their building:

• manual,
• interactive,
• automatic, for block of two identical parts.

In version 5, also are developed new complex methods for:

• Creation of matrices of identical, rectangular parts with common cuts.
• Automatic common nesting, with or without control of common corner of the part with neighbor part.
• Automatic creation of common cuts on multitude of common parts with control of 'islands' of uncut paths.
• Interactive creation of common cuts with control of 'islands' of uncut paths.

The methods for creation of matrices with common cuts are included in Vintech RCAM, and the rest of the methods in Vintech RCAM-Pro.

Now it is possible, at any time, to choose interactive or automatic creation of common cuts, and the control of 'islands' of uncut paths is permanent.

When the common cuts are created automatically, is possible to:

• Preprocess holes in parts with common cuts,
• Automatic completion of partially connected common cuts,
• Automatic creation of complete route – sequence of rapid moves and cutting moves throughout the nesting.

When the common cuts are created interactively, is possible to:

• Reverse the direction of the common path by pointing,
• Create uncompleted sequences of common cuts.

In RCAM-Pro the functions for automatic and interactive creation of common cuts are united in general interface, including the methods for automatic creation of paths and route.

Notes:

Common nesting, is nesting of contours or contour segments of neighbor parts, where the contours of two parts are on a distance exactly one cutting diameter. Vintech RCAM is nesting commonly only along linear contour segments.

Common paths, are completely overlapping parts of cutting paths when walking around neighbor parts. In the true shape nesting technology, the re-cutting of already cut path, is generally intolerable. In Vintech RCAM are developed functions, which allow deleting one of both common paths.

Common cut, is sequence of cutting moves and rapid moves, through which common nested parts are separated with only one cutting move.
