What are the causes of errors in Lathe Machines?
1. The test error of the detection system includes the following aspects:
(1) The error of the measurement sensor feedback system itself caused by the manufacturing error of the measurement sensor and its installation error on the machine tool;
(2) Errors in measuring sensors due to machine tool parts and mechanism errors and deformations in use.
2. External interference error: random error caused by changes in the environment and operating conditions.
3. The error caused by the deformation of the process system caused by the cutting load: including the error caused by the deformation of the machine tool, tool, workpiece and fixture. This kind of error is also called "letting the knife", which causes the shape distortion of the machined part, especially when machining thin-walled workpieces or using slender tools, this error is more serious.
4. Vibration error of the machine tool: During the cutting process, the Lathe Machine has a greater possibility of falling into the unstable area due to the flexibility of the process and the changeable process, thus causing strong chatter. Lead to the deterioration of the surface quality of the machined workpiece and geometric errors.
5. Original manufacturing error: refers to the motion error caused by the geometric shape, surface quality, and mutual position error of the working surface of the components of the Lathe Machine, which is the main reason for the geometric error of the machine tool.
6. Control system error: including servo error of Lathe Machine shaft system (contour following error) and interpolation algorithm error.
7. Thermal deformation error: The error caused by the thermal deformation of the machine tool structure caused by the internal heat source of the equipment and the thermal disturbance of the environment.
8. Other errors: such as errors caused by programming and operation errors.
