Checking the program
You can check the following:
● Does the programmed workpiece have the correct shape?
● Are there large traversing errors?
● Which program block hasn't been correctly programmed?
● How is the approach and retraction realized?
NC blocks that can be interpreted
The following NC blocks are supported for the mold making view:
● Types
– Lines
– Circles
– Absolute data AC and incremental data IC are possible
– For G2, G3 and different radii at the start and end, an Archimedes spiral is used
● Orientation
– Rotary axis programming with ORIAXES or ORIVECT using ABC for G0, G1, G2, G3,
– Orientation vector programming with ORIVECT using A3, B3, C3 for G0, G1, G2, G3,
– Rotary axes can be specified using DC
● G codes
– Working planes (for circle definition G2, G3): G17 G18 G19
– Incremental or absolute data: G90 G91
The following NC blocks are not supported for the mold making view:
● Helix programming
● Rational polynomials
● Other G codes or language commands
All NC blocks that cannot be interpreted are simply overread.
