Abstract: The present invention demonstrates a halfway cutter changing method for large-area microstructure cutting based on in-situation film thickness measurement, including the following steps: step 110: preparatory work; step 120: workpiece preliminary machining; step 130: transparent film coating; step 140: film thickness detection; step 150: halfway cutter changing; and step 160: machining completion. The halfway cutter changing method for the large-area microstructure cutting based on the in-situation film thickness measurement provided by the present invention implements machining of a microstructure with large area, high quality and high uniformity.

Abstract: An internal-cooling rolling tool capable of realizing variable-angle low-temperature lubrication is provided. The internal-cooling rolling tool includes a tool handle, a rotatable tool head and a medium conveying tube. The rotatable tool head includes a base, a rolling head and a ball. The bottom end of the base is mounted on the tool handle, and the top of the base is provided with a medium input port connected with the medium conveying tube. The rolling head is detachably mounted on the front end surface of the base, and the front end surface of base is provided with a plurality of spray holes in the circumferential direction of the rolling head. The medium conveying tube communicates with the spray holes through a medium flow channel. The ball is mounted on one end of the rolling head facing away from the base.
