Abstract

The invention discloses a numeric control processing method for a single-curvature-degree coating a chemically-milling sample plate. The numeric control processing method comprises the following steps of: expanding theoretical data of a single-curvature-degree coating to be chemically milled to form a two-dimensional planar graph through a computer system; obtaining a plane sample plate by numeric control processing; and finally, forming the single-curvature-degree coating chemically-milling sample plate. According to the numeric control processing method, the automatic manufacturing degree of the chemically-milling sample plate is improved, the production efficiency is greatly increased, favorable compatibility of a plurality of sample plates during milling for multiple times can be ensured and the consistent processing deviation (-0.08) is obtained.

Example Embodiment

[0012] The present invention is a numerical control processing method for a single-curvature skinned milling template, which mainly includes the following steps: firstly, the theoretical data 1 of a single-curvature skinned part that needs to be milled is expanded by a computer system to form a two-dimensional plane figure 2; Secondly according to the two-dimensional plane figure 2 Compile the numerical control processing program; again use the plane numerical control processing technology to process the plane template 4 on the sample plate to be processed; finally, press the reverse cut outer template 6 to form the single curvature milling template 10.
[0013] figure 1 Shown is that the theoretical data 1 of the part is expanded by computer software to form a two-dimensional plane figure 2 , There is a milling mark line 3 on the expanded plan view. figure 1 The milling mark line 3 shown in the figure generally includes the girder axis, the milling end line, and the frame axis. Project the milling marking line 3 onto the two-dimensional plan. Because it is a single-curvature profile, the error after unfolding is very small and negligible. Then according to the two-dimensional plane figure 2 Compile a CNC machining program. figure 2 In order to process the shape of the plane template 4, the milling mark line 3, and the milling area viewport 5 on the sample plate to be processed by the plane numerical control processing technology. image 3 The plane template 4 is rolled and formed into a single curvature milling template 10. The reverse cut outer template 6 completely overlaps with the outer surface 8 of the milling template, and the inner cutting template 7 completely overlaps with the inner surface 9 of the milling template. Press image 3 The inverted outer template 6 in the middle is rolled into a flat template 4 after CNC machining, that is, the template is formed from a flat state to a curved state, and finally the single-curvature milling template 10 is checked according to the in-cut sample 7 and the size of the milling marking line 3. Finish processing. It’s worth reminding that image 3 The milling mark line 3 and the milling area viewport 5 are not shown on the medium single curvature milling template 10.
[0014] Practice has proved that it is a practical and feasible high-efficiency processing method to use plane numerical control processing first and then bend and form, and the final inspection result fully meets the technical requirements.
