Types of coordinate Axis control systems include Cartesian, polar, cylindrical, and spherical systems.

• Cartesian coordinate system uses three perpendicular axes (X, Y, Z) to define positions in 3D space.

• Polar coordinate system uses a distance from a fixed point (origin) and an angle from a reference direction.

• Cylindrical coordinate system adds a height component to the polar system, defining positions in 3D space.

• Spheri...read more
