Abstract
The invention discloses a control mode for realizing high-efficiency dry running in a numerical control system, which is based on the surface following function of a height sensor in the numerical control system to realize non processing time compression and cause laser processing to be efficient on the premise of ensuring that equipment is safe. The control mode comprises setting a retraction height H and a preset distance D before dry running ends, thus three actions of the existing laser processing are combined into one action to finish, i.e. a processing head quickly moves to the next processing position directly at dry running speed; in the process, the processing head retracts to the preset height H at the maximum speed and begins falling when the processing head does not reach the next processing point (distance D away from the next processing point), thus reducing non processing time of the equipment and greatly improving the using efficiency of the equipment.

Such as, in traditional digital control laser cutting, in the control mode of cutting head operation between the cutting process section as shown in Figure 1: close the height tracing function earlier after cutting a program segment (position 1), and the height (position 2) that the Z cutting head program of retracting to is set, how much axis servomotors began to carry out dry running after retraction put in place, after moving the cutting position (position 3) of next program segment, cutting head opens height tracing again, and carry out the action of bowing, after putting (position 4) in place, cutting head decline begins to carry out the cutting of next program segment.In such one-period, when dry running, it is earlier with the cutting head withdrawal, and translation then arrives and cutting head descended after the next cutting profile starting point and follow on the beginning surface again.This mode can be avoided causing cutting head and material to bump because of the plate surface height is inconsistent when dry running effectively, but right and wrong are just long process time, and the instream factor of equipment is not high.
Summary of the invention
Technical matters to be solved by this invention provides the control mode that realizes efficient dry running in a kind of digital control system, this control mode is being followed function based on the height sensor surface exactly, realize the compression of non-process time, make Laser Processing under the prerequisite that guarantees device security, become more efficient.
For solving the problems of the technologies described above, the technical solution used in the present invention is to realize the control mode of efficient dry running in a kind of digital control system, comprise in this control mode and set a retraction predetermined altitude H, finish preceding preset distance D with a dry running, may further comprise the steps
(1) carrying out a job sequence finishes;
(2) judge processing head apart from the actual range d of next processing stand whether greater than preset distance D, if, execution in step (3), otherwise, execution in step (4);
(3) whether judge the actual retraction height of processing head h less than predetermined altitude H, if, execution in step (6), otherwise, execution in step (8);
(4) carry out translation, open the surface and follow;
(5) judge whether processing head arrives Working position, if, execution in step (11), otherwise, execution in step (4);
(6) retraction and translation;
(7) judge processing head apart from next processing stand actual range d whether greater than preset distance D, if, execution in step (3), otherwise, execution in step (9);
(8) continue translation and stop retraction, return step (7);
(9) decline and translation processing head are opened the surface and are followed;
(10) judge whether processing head arrives Working position, if, execution in step (11), otherwise, execution in step (9);
(11) carry out processing.
After using control mode of the present invention, the advantage that not only has security of operation, and can with have now in the Laser Processing three actions be merged into an action and finish, be that processing head directly moves quickly into next Working position with dry running speed, processing head at full throttle retracts to earlier predetermined altitude H in this course, when going back no show next one processing stand, just begins to descend, so just reduce the non-process time of equipment, improved the service efficiency of equipment greatly.
