Type Axis command
Syntax B_SPLINE(type, data_in, number_in, data_out, #expand)
Description Expands an existing profile stored in the TABLE using the B-Spline
mathematical function. The expansion factor is configurable and the
B_SPLINE stores expanded profile to another area in the TABLE.
This is ideally used where the source
CAM profile is too course and
needs to be extrapolated into a greater number of points.
Arguments • type
Reserved for future expansion. Always set this to 1.
• data_in
Location in the TABLE where the source profile is stored.
• number_in
Number of points in the source profile.
• data_out
Location in the TABLE where the expanded profile will be stored.
• expansion_ratio
The expansion ratio, i.e., if the source profile is 100 points and
expansion_ratio is set to 10 the resulting profile will be 1000 point
(100 * 10).
Example BASE(1)
B_SPLINE(1, 0, 10, 200, 10)
This command expands a 10 point profile in TABLE locations 0 to 9 to a
larger 100 points profile starting at TABLE location 200.
