Engaged in indexing chuck, often encounter a problem, that is, the English vocabulary about CNC, sometimes for some of the professional vocabulary is not very clear. Today we have summarized the English vocabulary of CNC. We hope that you can learn it carefully and make up for your own knowledge.

1) Computerized numerical control (CNC) realizes numerical control by controlling processing function with computer.

2) The parts of Axis machine tools can move in a straight line or in a rotary direction.

3) Machine Coordinate Systern is fixed on the machine tool and Cartesian coordinate system is based on the zero of the machine tool.

4) The origin of machine coordinate Origin.

5) Workpiece Coordinate System Fixed to Cartesian coordinate system of workpiece

6) Workpiece coordinate origin (Wrok-piexe Coordinate Origin) Workpiece coordinate system origin.

7) Machine zero is the origin of the machine set by the machine tool manufacturer.

8) Reference Position A fixed point along a coordinate axis for starting a machine tool. It can use the origin of the coordinate of the machine tool as a reference point.

9) Absolute Dimension/Absolute Coordinations: the straight line distance or angle from the origin of a coordinate system.

10) Incremental Dimension/Incremental Coordinates are increments of a sequence of points, the distance or angle between each point and the preceding point.

11) Least Input Increment (Least Input Increment) is the smallest incremental unit that can be input in the process.

12) Least command Increment (LEST command Increment) is the smallest incremental unit of command axis movement from a numerical control device.

13) Interpolation is the process of calculating the coordinate values of the positions of multiple intermediate points between two known points on the required path or contour line according to a mathematical function (e.g. straight line, arc or higher-order function).

14) Linear interpolation (Llne Interpolation) is an interpolation method, in which the interpolation between two points approximates along the point group of a straight line, along which the motion of the tool is controlled.

15) Circula: Interpolation is an interpolation method. In this way, according to the interpolation digital information between two endpoints, the point groups approaching the actual arc are calculated, and the tool movement along these points is controlled. The clockwise arc (Clockwise Arc) tool reference points revolve around the center of the track and form a trajectory in a negative direction. The trajectory formed by directional rotation.

17) The counterclockwise Arc tool reference point revolves around the center of the trajectory in a positive direction.

18) Manual Part Prograrnmiog (Manual Part Prograrnmiog) compiles the part processing program manually.

19) Computer Part Programming (Cornputer Part Programarnrnlng) prepares part program with computer and appropriate general processing program as well as post-processing program to get processing program.

Absolute Prograrnming is programmed with control words representing absolute size.

The above is the CNC English vocabulary of the indexing chuck. In fact, the process of learning English, once started, must persist, not give up halfway, even if only remember a few words every day, it is not a small progress, we say is not this high.
