A Blade Surface Flatness Measuring System Based on Laser Displacement Sensor for Knives and Scissors

摘要

In order to measure the blade surface flatness, which has a serious influence on the quality and its stability of knives and scissors quality, a blade surface flatness measuring system based on laser displacement sensor is established. This system has many advantages such as a high precision (0.001 mm), non-contact, convenient, simple operation, and so on. The system is very helpful to improve the product qualities of knives and scissors.
