sivicncdriver.arc_calculator module

The arc_calculator module

It creates small segments from an arc given with G-codes parameters : origin, end, path to center and sense of rotation.

Example:

>>> from arc_calculator import arc_to_segments
>>> a = arc_to_segments((0,0),(5,0),(10,0))
>>> for x,y in a:
...     print((x,y))
...

sivicncdriver.arc_calculator.arc_to_segments(start, vect_to_center, end, clockwise=False, length=1)

Creates small segments from an arc.

Uses Decimal for better precision. It yields the vertices.

Parameters:

• start (A float tuple) – The starting position
• vect_to_center (A float tuple) – A vector to go to the center of the arc from the starting position
• end (A float tuple) – The ending position
• clockwise (bool) – Should it go clockwise ?
• length (float) – length of the segments

Returns:

None, it yields vertices.
