Geometry

X CenterX	The distance from the origin of workpiece to the center of the arc in X direction.
Y CenterY	The distance from the origin of workpiece to the center of the arc in Y direction.
Z StartZ	The distance from the origin of workpiece to the upper surface of removed area in Z direction.
D Depth	Depth of removal.
R Radius	Radius of the arc.
S StartAng	Take the positive X direction as 0, and counter clockwise is positive. The angle of the line from center to the first point in this array.
A DeltaAng	The angular difference between two neighboring holes.
N Count	Count of holes.

Manufacture

ToolNumber		Order of desired tool in tool table.
SpindleRPM		Rotating speed of spindle.
SpindleDir	CW	Spindle rotates in CW.
	CCW	Spindle rotates in CCW.
H ZUpper		Z axis would halt at this position which is related to StartZ before and after drilling.
M HoleMode	Simple	Drill to the designated depth directly.
	Peck	Lift Z up a fixed distance after every step of drilling until reaching the designated depth.
	Retract	Lift Z up to the ZUpper after every step of drilling until reaching the designated depth.
Q StepDepth		Depth per drilling of peck/retract mode.
