The deflection of fixture and milling cutter is a common phenomenon in machining, and their respective definitions, causes and influences are different.
In machining, the deflection of the fixture is usually not the subject of direct discussion, because the main function of the fixture is to stably clamp the work and ensure the stability and accuracy in the machining process. However, if the fixture itself has design or installation problems, it may lead to unexpected displacement or vibration of the workpiece during machining, which can be indirectly regarded as the “deflection” effect of the fixture.
The deviation of milling cutter refers to the deviation between the axis of milling cutter and the predetermined trajectory during machining. This deviation may be caused by the lack of precision of machine tools, inaccurate fixture positioning, tool wear or improper installation.
Precautions:Please use a rigid high-precision milling cutter handle.When feeding the cutter, try to minimize the deflection of the cutter.
To sum up, the deflection of fixture and milling cutter is an important problem that needs attention in machining. Through reasonable design and maintenance measures, the occurrence of deflection phenomenon can be effectively reduced, and the machining accuracy and surface quality can be improved.
