Abstract
A cutting distance calculating device for a multi-axis working machine acquires axis positions at calculation times for at least three linear axes and two rotation axes of a multi-axis working machine and calculates the position of a tool tip point on the basis of the acquired axis positions. This device accumulates moving distances (cutting distances) of the tool tip points from the calculated position of the tool tip point to thereby calculate a cutting distance and predicts tool wear and tool life on the basis of the calculated cutting distance.
Claims7
A multi-axis working machine, comprising:
- at least three linear axes and two rotation axes;
- a tool driven by the at least three linear axes and two rotation axes, the tool having a tool tip point;
- and
- a cutting distance calculating device comprising:
- a positional-information acquiring section configured to acquire axis positions at calculation times for the at least three linear axes and two rotation axes;
- a tool-tip-point-position calculating section configured to calculate a tool tip point position of the tool tip point on the basis of the axis positions acquired by the position-information acquiring section;
- and
- a cutting-distance calculating section configured to accumulate moving distances of the tool tip point on the basis of the tool tip point position calculated by the tool-tip-point-position calculating section and set an accumulated moving distance as a cutting distance,
- wherein the cutting distance calculating device is configured to predict tool wear based on the cutting distance.
