12. It is not allowed to leave the work post when the machine tool is running. If you want to leave for any reason, put the worktable in the middle position, the tool bar should be retracted, you must stop the machine, and cut off the power supply of the host.
The operation points of CNC 4 Axis Machining:
1. In order to simplify positioning and installation, each positioning surface of the fixture should have precise coordinate dimensions relative to the machining origin of the machining center.
2. In order to ensure that the installation orientation of the parts is consistent with the direction of the workpiece coordinate system and machine tool coordinate system selected in programming, and directional installation.
3. It can be disassembled in a short time and changed into a fixture suitable for new workpieces. Since the auxiliary time of the machining center has been compressed very short, the loading and unloading of the supporting fixtures cannot take up too much time.
4. The fixture should have as few components as possible and high stiffness.
5. The fixture should be opened as much as possible, the spatial position of the clamping element can be lower or lower, and the installation fixture should not interfere with the tool path of the working step.
6. Ensure that the machining content of the workpiece is completely completed within the stroke range of the spindle.
7. For a 4 axis machining center with an interactive worktable, the fixture design must prevent spatial interference between the fixture and the machine due to the movement of the worktable, lifting, lowering, and rotation.
8. Try to complete all the processing content in one clamping. When it is necessary to replace the clamping point, special attention should be paid not to damage the positioning accuracy due to the replacement of the clamping point, and explain it in the process document if necessary.
9. For the contact between the bottom surface of the fixture and the worktable, the flatness of the bottom surface of the fixture must be within 0.01-0.02mm, and the surface roughness is not greater than Ra3.2um.
