Embodiment Construction

[0034] The present invention will be further described below in conjunction with specific embodiment:

[0035] Such as figure 1 As shown, the specific steps are as follows:

[0036] 1) At the beginning of the program, use the R parameter table to input the characteristic parameters of the roll and the grinding process parameters, select the AUTO mode, press the start button to start the main grinding program, and call the main grinding subroutine; wherein, the R parameter table is:

[0037] R0~R9: current grinding process parameters

[0038] R0-----current process number, range: 0~9

[0039] R1-----current carriage speed, range: 0~4000mm / min

[0040] R2-----current continuous compensation, range: 0~1.2mm / min

[0041] R3-----current cycle feed, range: 0~0.12mm / time

[0042] R4-----current trip times, range: 0~100 times

[0043] R9-----Current process combination, range: 00000~099999999, each bit 0~9

[0044] R10~R19: current grinding curve parameters

[0045] R10-----Cu...

Abstract

The invention discloses a method for realizing the numerical control of grinding roller curves by using an NC program, which pertains to the method by adopting the NC program to control grinding processing, and aims at providing a method that adopts the current NC program to realize the numerical control of the grinding roller curves by means of the definition setting of a R parameter under the state that a numerical control system runs automatically. The method comprises steps of defining variable, transferring curve data, judging grinding type, inspecting the curve data, pre-treating the data before grinding, reading technological parameters, judging processing modes, finishing grinding, judging whether to end the grinding or not, judging the time of strokes, inspecting technological data, judging whether to relocate or not, grinding in positive direction or negative direction, calculating curves, commutating processing, finishing grinding, calculating of the finishing of the grinding and quitting position calculation, etc. The method of the invention needs no specialists to write the NC program, can write program and store a plurality of grinding curves, groups of technological parameters of grinding and the technological parameters of disc finishing, and can be applied to Siemens middle and high grade numerical control systems programmed by adopting G code.

Description

Technical field: [0001] The invention relates to a method for controlling the curve of a grinding roll with a numerical control program, in particular to a method for realizing the curve of a numerically controlled grinding roll by using NC programming with the help of definition and setting of R parameters. Background technique: [0002] Roll grinder is an indispensable and important production equipment in metallurgy, papermaking, rubber and printing and dyeing industries. It is widely used for grinding cylindrical rolls with various sinusoidal (convex or concave), straight line, taper and other grinding curves. The roll grinder has some characteristics of the cylindrical grinder, but its transmission principle is much more complicated. In order to complete the convex or concave grinding of the roll shape, in addition to the relative rotary motion between the grinding wheel and the workpiece required by the cylindrical grinder, It is also required that the carriage moves b...
