Optionally, lathe includes at least: knife rest and tailstock, knife rest and tailstock are moving parts.
Above-mentioned lathe can be numerically controlled lathe (Computer Numerical Control, CNC), by CNC system into
Row control.Knife rest is the loading platform of cutter, and tailstock is the ancillary equipment of top tight workpiece, and two components add where lathe
It is moved in work plane, the two moving range causes to collide it is possible that intersection.
Fig. 1 is a kind of flow chart of Lathe control method according to an embodiment of the present invention, as shown in Figure 1, this method includes
Following steps:
Step S102 obtains the first coordinate of knife rest and the second coordinate of tailstock.
Knife rest and tailstock move in processing plane, and the position that knife rest and tailstock collide is random.In order to avoid occurring
Collision can construct the coordinate system of X-axis line and z axis composition in processing plane in advance.What knife rest moved in processing plane
Position can be considered as the first coordinate in the coordinate system, and the position that tailstock moves in processing plane can be considered as in the coordinate
The second coordinate in system.
CNC system has data acquisition function, can acquire the first coordinate of knife rest in real time by axis data acquisition device
With the second coordinate of tailstock.
Step S104 is based on the first coordinate and the second coordinate, judges knife rest and tailstock with the presence or absence of risk of collision.
Also there are CNC system data to analyze comparing function.In order to avoid knife rest and tailstock are hit, need to judge in advance
Knife rest and tailstock whether there is risk of collision, can preset a risk of collision range, get the first coordinate and the
After two coordinates, it can judge whether two coordinates are located at collision by comparing system according to the relative position of two coordinates
In risk range, to determine knife rest and tailstock with the presence or absence of risk of collision.
Step S106, determining knife rest and tailstock, there are in the case where risk of collision, control knife rest and tailstock stopping shifting
It is dynamic.
Determining knife rest and tailstock there are in the case where risk of collision, in order to avoid knife rest and tailstock continue to move toward one another
It collides, can will continue to move toward one another according to control process control knife rest and tailstock stopping by comparing system, and avoid knife
Frame and tailstock collide.
Above-described embodiment through the invention can be with after the second coordinate of the first coordinate and tailstock that get knife rest
Based on the first coordinate and the second coordinate, judge that knife rest and tailstock with the presence or absence of risk of collision, are determining knife rest and tailstock presence
In the case where risk of collision, controls knife rest and tailstock stops movement, realize the purpose of lathe anticollision control.With prior art phase
Than, no matter how the mobile position of knife rest and tailstock changes, can realize cutter setting frame and tailstock with the presence or absence of risk of collision into
