The Z-turn tool data of the CNC lathe tool is related to the clamping length of the tool on the tool holder and the Z-zero position of the workpiece coordinate system. It is used to determine the position of the zero point of the workpiece coordinate system in the machine coordinate system. Trial cutting of the knife, you can also use the Z-direction setter for accurate tool setting, the working principle is the same as the edge finder.
When the lathe is facing the knife, the end edge of the tool is also in contact with the surface of the workpiece or the probe of the Z-direction setter, and the value of the tool is determined by the display of the machine coordinate. When using the Z-direction setter for tool setting, consider the height of the Z-direction setter. In addition, since there are many tools used in the machining center, the distance between each tool and the zero point of the Z coordinate is different. The difference between these distances is the length compensation value of the tool. Therefore, it is necessary to measure each on the machine tool or the dedicated tool setting tool. The length of the tool (tool presetting) is recorded in the tool schedule for use by the machine operator.
The Z-direction tool on the machining center has the following two methods:
(1) Machine tool
The method uses the Z-direction setter to sequentially determine the mutual positional relationship between each tool and the workpiece in the machine coordinate system. The steps are as follows:
1. Install the tool on the spindle in turn, and use the Z-direction setter to determine the distance from each tool to the Z-th zero point of the workpiece coordinate.
2. Find the tool with the longest distance to the workpiece and set the tool value AG as the Z value of the workpiece coordinate system.
The method has high efficiency and precision for the knife, and the investment is small, but the process documentation is inconvenient to write, which has certain influence on the production organization.
(2) Off-machine tool pre-adjusting machine
The method firstly uses the tool presetter outside the machine tool to accurately measure the axial and radial dimensions of each tool, determine the length compensation value of each tool, and then perform Z-direction on the machine with the longest or shortest tool. For the tool, determine the workpiece coordinate system. This method has high precision and efficiency, and is convenient for the preparation and production organization of the process documents, and the investment is large.
