Cartesian Coordinates
When programming a part using MILLPWR , table movement and tool motion are
determined by the use of positive or negative numbers. MILLPWR has been factory set
with the following positive and negative directions for X, Y, and Z:
X-axis: the table will move to the left, with tool
motion to the right, for positive positions.
Y-axis: the table will move toward you while tool
motion is away from you for positive positions.
Z-axis: quill movements up (away from the table
surface) are for positive positions.
Polar Coordinates
The polar radius (R), is the distance from datum (absolute zero) to a point. The polar
angle (A), is formed by the X-axis and the radius, positive counter- clockwise. The
angle is always measured from the positive X-axis.
