One of the most popular terms used in numerical co

In order to facilitate readers to read relevant numerical control materials and relevant manuals of foreign numerical control products, common numerical control vocabulary and its English corresponding words are selected here. The selected numerical control terminology mainly refers to the international standard ISO 2806 and the national standard GB 8129 1987 of the people's Republic of China, as well as some new numerical control vocabulary in recent years

1) computerized numerical control (Purell rp320m used for casting film and injection molding processing has good mechanical properties, optical properties, excellent homogeneity and sealing performance CNC) uses computer control processing function to realize numerical control

2) the reference direction along which the components of the axis machine tool can move in a straight line or rotate

3) machine coordinate system is a Cartesian coordinate system fixed on the machine tool and based on the zero point of the machine tool

4) machine coordinate origin: the origin of the machine coordinate system

5) the workpiece coordinate system is the Cartesian coordinate system fixed on the workpiece

6) workpiece coordinate origin

7) machine zero is the machine zero specified by the machine manufacturer

8) reference position is a fixed point along the coordinate axis for machine tool startup, which can use the coordinate origin of machine tool as the reference datum

9) the linear distance or angle between absolute dimension/absolute coordinates and the origin of a coordinate system

10) incremental dimension/incremental coordinates is the distance or angle value between each point and the previous point in the increment of a sequence of points

11) least input incr (least input incr is measured by experimental equipment; element) is the minimum increment unit that can be input in the processing program

12) least command increment is the smallest increment unit of the command axis movement sent from the numerical control device

13) interpolation is the operation process of determining the position coordinate values of multiple intermediate points between two known points on the required path or contour line according to a mathematical function (such as line, arc or higher-order function)

14) linear interpolation this is an interpolation method, in which the interpolation between two points is approached along the point group of the line, and the movement of the tool is controlled along the line

15) circular: interpolation this is an interpolation method. In this method, according to the interpolation digital information between the points at both ends, the point group approaching the actual arc is calculated, and the cutter is controlled to move along these points to process the arc curve

16) a container for finding a low point formed by rotating the clockwise arc tool reference point around the center of the track in a negative angle direction; Track The track formed by direction rotation

17) counter clockwise arc is a track formed by rotating the tool reference point around the center of the track in a positive angle direction

18) manual part programming (manual part Prograrnm adds 1 settable parameter - initial running speed of instrument (V0) IOG) to manually compile the part processing program

19) corncomputer part prograrnnlng prepare the part program with computer and appropriate general processing program and post-processing program to obtain the processing program

20) absolute programming is programmed with a control word representing the absolute size

21) increment programming is programmed with a control word representing the increment size

22) character is a group of element symbols used to represent an organization or control data

23) control character appears in specific information text and represents a character of a control function

24) address a character or group of characters at the beginning of a control word to identify the subsequent data

25) block format the arrangement of words, characters and data in a program segment

26) instruction code/machine code computer instruction code, machine language, the code used to represent the instructions in the instruction set

27) program number: the number assigned at the front of each program when identifying the processing program with a number
