Title:
STABILITY LIMIT CHART CREATION DEVICE AND STABILITY LIMIT CHART CREATION METHOD
Document Type and Number:
Japanese Patent JP2018126837
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a stability limit chart creation device and so on by which a proper stability limit chart in line with actual processing can be created.SOLUTION: This stability line chart creation device comprises: a vibration detection part 2 which detects vibration of a vibration system which is generated when processing a work-piece by a tool; a chatter detection part 3 which analyzes vibration detected by the vibration detection part 2, and associates a regenerative chatter frequency at the time of generation of regenerative chatter in the tool with a spindle rotational speed and stores the same in a data storage part 4; a calculation part 5 which calculates an optionally set attenuation ratio of the vibration system based on combination of the tool, a tool holder, a work fixing jig and a machine tool, and calculates a characteristic frequency of the vibration system based on the regenerative chatter frequency stored in the data storage part 4 and the spindle rotational speed; a chart creation part 6 which creates a stability limit chart based on the regenerative chatter frequency stored in the data storage part 4 and the spindle rotational speed; and a display 7 which displays the stability limit chart created by the chart creation part 6.SELECTED DRAWING: Figure 2
