ABSTan CAD-CAM

The ABSTan program is developed by LM ZONE, and its purpose is for rapid creating and edit simple shapes and mattresses, organizing and arranging shapes in a block of PU foam, generating g-codes for executing cuts with special cnc machines. Unlike all conventional programs, the ABSTan program performs contour interpolation, tangential angle calculation, draft analysis, and creation of cnc g-codes immediately during drawing. By loading a dxf v.12 file, the operator determines in which smoothness the drawing will be loaded, if the drawing from Autocad is exported as Bulge/Arc entities. If the design is exported as a “polyline” (usually if draft contain splines, or arcs was scaled), the smoothness is defined during the export and the Abstan program cannot change it. 

The operator himself determines the angle to which the interpolation point will be made (all three axes in motion) the rotation of the knife and the movement of the X and Y axes, i.e. when the movement stops, the knife is turned, and the movement continues.

The operator has absolute control over the style and way of movement of the knife through the cut material, he determines from which point and in which direction the cutting will start, individually for each shape. Usually the program itself searches for free paths to move from shape to shape, however, it is also possible for the operator to manually determine it.

The ABSTan program contains a number of common predefined shapes, which simply define a complete mattress, and clone it to the desired quantity in a few minutes.

Drawings created by the ABSTan program can be used on machines of other manufacturers on two ways

• save design as DXF files  ( no prerequisities )
• save design as CNC file ( with prerequisities  as below)
• complete steering with programs can be ordered on mail request (price depend of servo sizes)

prerequisites for machine: G 04 must be in mSec, blade rotating axis must be defined as Z, full rotation of axis must be scaled by 10 and defined as non-rotational (-36 to +36 degree for oscillating machine) G90,G91,G92 must be suported
