In order to facilitate readers to read relevant CNC data and related manuals for foreign CNC products, the commonly used NC vocabulary and its English corresponding words are selected here. The selected NC terminology mainly refers to the international standard ISO2806 and the National Standard of the People's Republic of China GB8129-1987 and recent years. Some new CNC vocabulary.
1) Computerized Numerical Control (CNC) uses a computer to control the machining function to achieve numerical control.
2) The axis (Axis) machine tool can be moved along its direction of linear or rotary motion.
3) The machine coordinate system (MachineCoordinateSystern) is fixed on the machine tool, and the Cartesian coordinate system based on the machine zero point.
4) Machine coordinate origin (MachineCoordinateOrigin) The origin of the machine coordinate system.
5) The workpiece coordinate system (WorkpieceCoordinateSystem) is fixed to the Cartesian coordinate system on the workpiece.
6) Workpiece coordinate origin (Wrok-piexeCoordinateOrigin) The origin of the workpiece coordinate system.
7) Machine zero is the origin of the machine specified by the machine tool builder.
8) ReferencePosition A fixed point along the coordinate axis used to start the machine. It can be referenced to the machine coordinate origin.
9) Absolute Dimension / Absolute Coordinates The linear distance or angle from the origin of a coordinate system.
10) Incremental Dimension / Incremental Coordinates In the increment of a sequence of points, the distance or angle value of each point from the previous point.
11) Least Input Increment The minimum increment unit that can be entered in the machining program.
12) Command Increment (LeastcommandIncrement) The minimum increment unit of the command axis movement from the numerical control device.
13) InterPolation determines the position coordinate values ​​of multiple intermediate points between two known points on the desired path or contour according to a mathematical function (for example: straight line, arc or higher order function) The operation process.
14) Linear interpolation (LlneInterpolation) This is an interpolation method in which the interpolation between two points is approximated along a linear point group, along which the movement of the tool is controlled.
15) Circular interpolation (Circula: Interpolation) This is an interpolation method. In this method, according to the interpolation digital information between the two ends, the point group that approximates the actual arc is calculated, and the control tool moves along these points. , the arc curve is processed.

Plane ruled gratings are characterized by a superior efficiency at their design wavelength compared with holographic gratings. Plane Ruled gratings comprise the majority of diffraction gratings used in spectroscopic instrumentation and are especially useful in systems requiring high resolution.
China star optics can provide customers with a variety of replicated grating products such as diffraction gratings, reflective gratings,holographic gratings,concave gratings etc. to meet different needs. Maximum ruled area is up to 300 x 300 mm for plane ruled diffraction gratings. For replicated diffraction and transmission gratings the ruling density can be from 20 grooves per millimeter to 2400 grooves per millimeter, wavelength from 0.2 micron to 25 microns.
