Problems solved by technology

In the three-coordinate measurement technology, the radius of the stylus can be canceled for two-dimensional curve measurement, so that the test technical requirements can be reduced, but the generation of isometric curves can only be completed by improving the data processing level or CAD/CAM application ability, which is difficult for ordinary testers to achieve. Such a theoretical level and application ability, because the

Embodiment Construction

[0040] like figure 1 As shown, the cam two-dimensional curve measuring method of the present invention comprises:

[0041] Parabolize the two-dimensional curve of the cam;

[0042] The two-dimensional curve of the parabolized cam is measured by isometric measurement method.

[0043] like Figure 9 As shown, the steps further include the steps of parabolizing the two-dimensional curve of the cam:

[0044] 1) Set the measurement range of the cam two-dimensional curve in the given measurement direction;

[0045] 2) Collect n measurement points within each measurement range.

[0046] like Figure 9 Shown, described step adopts isometric measuring method to measure the following steps of the cam two-dimensional curve that parabolizes:

[0047] 3) Set the variable I from 1 to n in each measurement range, I is initially 1, and perform the following operations:

[0048] 4) Judging whether I is equal to N, if they are equal, then end;

[0049] 5) Turn off the stylus radius comp...

Abstract

The invention discloses a method capable of accurately measuring cam two-dimensional curves, which relates to the technical field of measuring and detecting the cam two-dimensional curves. The method comprises the following steps: the cam two-dimensional curves are changed into parabolic curves, and then, the cam two-dimensional curves which are changed into the parabolic curves are measured by an equidistant measuring method. The technical scheme of the method capable of accurately measuring the cam two-dimensional curves has high measuring accuracy.

Description

technical field [0001] The invention relates to the technical field of surveying and testing two-dimensional curves of cams; it is especially suitable for precision measurement and reverse engineering of cams and two-dimensional curve series parts in tobacco machinery, and is also suitable for mold manufacturing, machinery manufacturing and other fields. Rapid mapping, inspection and reverse engineering of two-dimensional curves on the measuring machine. Background technique [0002] A small part of the inspection of two-dimensional curves such as cams can be used with a universal tool microscope. Since manual measurement and data recording are required, the efficiency is low and the data processing is more complicated. Since its measuring range is generally 100×200mm, the measurement workpiece is small and can only be completed. Simple planar cams are difficult to do reverse engineering; some of them are completed with professional cam measuring instruments, but they are ge...
