1.01 About the coordinate system
The dispenser operates according to the space position of the program points in the program file.
Teaching space position of edit point is to record the coordinates of the program point relative to
the coordinate system.
Coordinate system: In order to explain the position of the particle, the speed of the motion and
the direction, the coordinate system must be selected. In the frame of reference, an ordered set
of data selected according to the prescribed method to determine the position of a point in
spaceis called “coordinates”. The method of specifying coordinates in a problem is the coordinate
system used for the problem.
There are many types of coordinate systems. The commonly used coordinate systems are: polar
coordinate system, Cartesian coordinate system, etc.
Polar coordinate system: Refers to the coordinate system composed of pole, polar axes and polar
diameters in the plane, denoted as P(ρ, θ), as shown below. The spherical coordinates can be
regarded as the spatial generalization of the polar coordinate system. It takes the coordinate
origin as the reference point and is composed of azimuth, elevation and distance,denoted as P(r,
θ, φ), as shown below. The cylindrical coordinate system can also be regarded as a spatial
extension of polar coordinates, as shown below.
Plane polar coordinate system Spherical coordinate system Cylindrical coordinate system
Cartesian coordinate system: The three non-coplanar number axes intersecting at the origin
form the affine coordinate system of the space. An affine coordinate system with equal units of
measure on three axes is called a space Cartesian coordinate system. The Cartesian coordinate
system in which the three axes are perpendicular to each other is called the space Cartesian
rectangular coordinate system, or else it is called the space Cartesian oblique coordinate system.
The machining of CNC machine tools is done by program control, so the determination and use of
the coordinate system is very important. According to the ISO 841 standard, the CNC machine
tool coordinate system is determined using the right-hand Cartesian coordinate system as a
standard. The CNC lathe is parallel to the main axis direction, that is, the longitudinal direction is
