Informativity of the Vibration Signal of the Spindle Unit of the Metal Cutting Machine

Monitoring the condition of spindle units modern metal-cutting machines by methods non-selective diagnostics involves possibility installing monitoring sensors in places with maximum vibration information. In this regard, assessment informative value field unit, which can be carried out advance, taking into account design features, geometric and dimensional characteristics, is an urgent task. Based on energy approach, a computational model based median planes walls proposed using example universal lathe unit. On basis calculated model, balance equations are drawn up conditions for transmission power between housing. The dependences that allow us to calculate coefficients take absorption housing given. solution made it possible, level flow, rank unit body information content,. resulting used determine reference values velocities formed from sources absence defects. This will detect occurrence defect at early stage, presence assess its development.
