the center of the travel vector. A vector perpendicular to the travel vector [-y,x] is scaled to the

length of h [-y/d*h, x/d*h] and added to the center of the travel vector [x/2,y/2] to form the new point

[i,j] at [x/2-y/d*h, y/2+x/d*h] which will be the center of our arc.

r_T = [cos(phi) -sin(phi);

|

|

For arc generation, the center of the circle is the axis of rotation and the radius vector is
|
||||
defined from the circle center to the initial position. Each line segment is formed by successive
|
||||
vector rotations. This requires only two cos() and sin() computations to form the rotation
|
||||
matrix for the duration of the entire arc. Error may accumulate from numerical round-off, since
|
||||
all double numbers are single precision on the Arduino. (True double precision will not have
|
||||
round off issues for CNC applications.) Single precision error can accumulate to be greater than
|
||||
tool precision in some cases. Therefore, arc path correction is implemented.
|
||||
|
||||
Small angle approximation may be used to reduce computation overhead further. This approximation

holds for everything, but very small circles and large mm_per_arc_segment values. In other words,
|
||||
theta_per_segment would need to be greater than 0.1 rad and N_ARC_CORRECTION would need to be large
|
||||
to cause an appreciable drift error. N_ARC_CORRECTION~=25 is more than small enough to correct for
|
||||
numerical drift error. N_ARC_CORRECTION may be on the order a hundred(s) before error becomes an
|
||||
issue for CNC machines with the single precision Arduino calculations.
|
||||
|
||||
This approximation also allows mc_arc to immediately insert a line segment into the planner
|
||||
without the initial overhead of computing cos() or sin(). By the time the arc needs to be applied
|
||||
a correction, the planner should have caught up to the lag caused by the initial mc_arc overhead.
|
||||
This is important when there are successive arc motions.
