NC blocks that can be interpreted
Following NC blocks are supported for the mold building view.
● Types
– Lines
– Circles
– Polynomial
– B-splines
– 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,
– Rotary axis programming with ORIAXES or ORIVECT using PO[A] POS[b] PO[C] for
– Orientation vector programming with ORIVECT using A3, B3, C3 for G0, G1, G2, G3,
– Orientation curve with ORICURVE using XH, YH, ZH, for G0, G1, G2, G3, CIP, POLY,
– Orientation curve with ORICURVE using PO[XH] PO[YH] PO[ZH] for POLY
– 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
Following NC blocks are not supported for the mold making view.
● Helix programming
● Rational polynomials
● Other G codes or language commands
All blocks that cannot be interpreted are simply ignored
