一、无接触仿形的提出无接触仿形是在光电跟踪实践的基础上提出来的。前者跟踪样板,后者跟踪图线。由于图线的绘制误差较大,使产品的尺寸精度受到影响。故提出直接对样板进行仿形。样板既是加工依据也是检验依据。此外,这种仿形还适用于模具制造,可利用阳模来仿制阴模。目前,为了解决曲线加工,除用数控外,还可用液压仿形,但光电仿形与前两者比较,有它的优点:
First, non-contact profiling Proposed non-contact profiling is based on the photoelectric tracking practice put forward. The former tracking model, the latter tracking diagram. Due to the plot error of drawing lines, the dimensional accuracy of the product is affected. It is proposed to copy the template directly. Model is not only processing basis but also test basis. In addition, this profiling is also suitable for mold making, which can be modeled using a male mold. At present, in order to solve the curve processing, in addition to using NC, but also hydraulic profiling, but the optical profiling compared with the former two, has its advantages:
