Problems solved by technology

However, there are some disadvantages such as expensive equipment, difficult detection of diamond tool wear, and non-single-point contact on the machining track.
Therefore, there is a problem of inconsistency in surface accuracy of mass-produced products, resulting in low production efficiency
[0003] There are two errors in the path trajectory written by the programming software, one is the design error of building the model, and the other is the calculation error of calculating the trajectory. After the two errors are superimposed, plus the processing error of the extra bed, it is difficult to process a workpiece that meets the design requirements.

The production effect is high, and the precision of products is good.

Description

technical field [0001] The invention belongs to the technical field of lens processing, and in particular relates to an aspheric grinding device controlled by a macro program and a use method thereof. Background technique [0002] At present, aspherical lenses in the domestic market are almost all completed by diamond single-point lathes. Since foreign equipment has accumulated decades of experience in this field, there are mature systems and equipment. However, there are some disadvantages such as expensive equipment, difficult detection of diamond tool wear, and non-single-point contact on the machining track. Therefore, there is a problem of inconsistency in surface precision of products produced in batches, resulting in low production efficiency. [0003] There are two errors in the path trajectory written by the programming software, one is the design error of building the model, and the other is the calculation error of calculating the trajectory. After the two errors...
