Abstract

The present invention relates to a kind of three laser cutting heads and cut the Cutting road planning method of a workpiece simultaneously.Comprise the following steps: be identified cutting pattern judging, according to cutting rule, respectively specify that 1#, 2#, 3# cutting head, calculate figure the need of interrupting, input perforation means, gage system, cutting parameter and the penetrating parameter corresponding with cutting plate, automatically generate cutting process, and add rim charge process and broken limit process route plan.Same workpiece is cut by the present invention by using three laser cutting heads simultaneously, and plan three laser cutting head difference cutting routes, make three laser cutting heads close for clipping time simultaneously, ensure that whole cutting efficiency is the highest, improve the efficiency of 40% 100% relative to single laser cutting head.

Description

A kind of three laser cutting heads cut the Cutting road planning method of a workpiece simultaneously
Technical field
The present invention relates to a kind of three laser cutting heads and cut the Cutting road planning method of a workpiece simultaneously.
Background technology
Typically all using CAM software programming in laser cutting system, this CAM software is to generate machine by computer programming The NC code that bed apparatus can read, so that machine tool runs, more accurately, more efficiently, saves substantial amounts of for enterprise Cost.Adopt to be considered when CAM software is programmed one to key challenge is how to improve cutting efficiency.If cutting efficiency Too low, processing cost will necessarily be increased, cause enterprise competitiveness to decline.In cutting process, the sky that laser head path comprises The length moved is the bottleneck of restriction cutting efficiency.For there being the figure of multiple profile, different cutting sequences can produce different Empty shifting length.The purpose of path optimization finds a cutting path exactly, makes empty length of moving the shortest, must is fulfilled for again laser Some particular/special requirement of cutting technique.
Existing cut substantially uses a laser cutting head to cut workpiece, in cutting process, and meeting There is repeatedly empty shifting, cause cutting route long, inefficiency.
Summary of the invention
For drawbacks described above, it is an object of the invention to provide a kind of optimizing incision route, three laser cutting heads are simultaneously Carrying out cutting workpiece, shorten clipping time, a kind of three laser cutting heads improving cutting efficiency cut cutting of a workpiece simultaneously Cut paths planning method.
For this technical solution adopted in the present invention it is:
Comprise the following steps:
The first step: by software, cutting pattern is identified, judges, it is judged that condition include: the size of cutting pattern, cutting Material classification and thickness of slab and cutting assist gas type；
Second step: call cutting parameter table according to the condition of the first step, sorts out the time required for every section of line of cut, including cutting Cut time, aperture time, lead-in wire time, the quick traveling time of cutting head；
3rd step: just surely cut rule, respectively specify that 1#, 2#, 3# cutting head；
4th step: according to graphic length, calculate the size and number of times needing to interrupt；
5th step: carry out three cutting head cutting balance tests, three cutting heads are close for clipping time simultaneously so that whole cutting Efficiency is the highest；
6th step: manually adjust data, carries out empty preview, determines cutting path scheme；
7th step: add rim charge and process and broken limit processes route plan, recall the perforation means corresponding with cutting plate, draw Line mode, cutting auxiliary gas type, cutting parameter and penetrating parameter, automatically generate cutting process.
As the further improvement of technique scheme, it is fixed course or length that described rim charge processes, to sideline, both sides Cut off, it is simple to the collection of waste material limit silk.
As the further improvement of technique scheme, it is that the clout in the middle of figure cuts that described broken limit processes, Clout is avoided to be less than minimum cut size, it is to avoid to affect the continuous operation of plate.
The invention have the advantage that
The present invention is by using three laser cutting heads to cut same workpiece simultaneously, and plans three laser cutting heads not Same cutting route so that three laser cutting heads are close for clipping time simultaneously, it is ensured that whole cutting efficiency is the highest, relative to single Laser cutting head improves the efficiency of 40%-100%.
Detailed description of the invention
A kind of three laser cutting heads cut the Cutting road planning method of a workpiece simultaneously, it is characterised in that include with Lower step:
The first step: by software, cutting pattern is identified, judges, it is judged that condition include: the size of cutting pattern, cutting Material classification and thickness of slab and cutting assist gas type；
Second step: call cutting parameter table according to the condition of the first step, sorts out the time required for every section of line of cut, including cutting Cut time, aperture time, lead-in wire time, the quick traveling time of cutting head；
3rd step: just surely cut rule, respectively specify that 1#, 2#, 3# cutting head；
4th step: according to graphic length, calculate the size and number of times needing to interrupt；
5th step: carry out three cutting head cutting balance tests, three cutting heads are close for clipping time simultaneously so that whole cutting Efficiency is the highest；
6th step: manually adjust data, carries out empty preview, determines cutting path scheme；
7th step: add rim charge and process and broken limit processes route plan, recall the perforation means corresponding with cutting plate, draw Line mode, cutting auxiliary gas type, cutting parameter and penetrating parameter, automatically generate cutting process.
As the further improvement of technique scheme, it is fixed course or length that described rim charge processes, to sideline, both sides Cut off, it is simple to the collection of waste material limit silk.
As the further improvement of technique scheme, it is that the clout in the middle of figure cuts that described broken limit processes, Clout is avoided to be less than minimum cut size, it is to avoid to affect the continuous operation of plate.
