Description
Technical field
The present invention relates to knife-changing systems intelligent in a kind of process based on decision Tree algorithms, are applied in five-axis robot
The heart, during processing and milling when there is tool failure, system can intelligent independent carry out selecting knife tool changing.
Background technique
In traditional tool changing mode, selection to cutter, the opportunity of tool changing relies primarily on the warp of programming personnel, technologist
It tests, appears in cutter and be also able to satisfy just tool changing in advance in the case where processing request；Or cutter is no longer satisfied processing request,
Lead to tool changing not in time since abnormal phenomenon is not obvious enough, to seriously affect machining accuracy, jeopardizes lathe or even operative employee
The personal safety of people, timely and effectively replacing cutter is the necessary means for improving process.
Summary of the invention
The present invention is the intelligent knife-changing system based on decision Tree algorithms building, first using knife parameter data set training decision
The algorithm model that training is completed is integrated into the tool change control software module write using C Plus Plus by tree algorithm.
The present invention is to realize that tool changing adopts the technical scheme that in process：Using tool change control software module as sub-line
Journey is embedded into the digital control system in open type of independent development.
The beneficial effects of the invention are as follows：Intelligent level in process is improved, is reduced since artificial tool changing generates
Downtime it is too long the problems such as.

Row mechanism controls program realizes tool changing action command, is driven by bottom intelligence tool changing hardware control device bsp driver hard
Part controls equipment work.
Specific embodiment two：Illustrate present embodiment in conjunction with Fig. 2 to Fig. 4, decision Tree algorithms model using fusion by adding
Work technique requires and the knife parameter data set training construction of process tool selection experience, in process, according to using cutter to join
Number, calculates replaceable cutter parameters in Tool Magazine in Machining Centers, selects replacement cutter, and knife result will be selected to inform that middle layer tool changing is held
Row mechanism controls program module, the tool changing that middle layer module is calculated according to decision Tree algorithms model select knife to change as a result, executing
Knife program, selects cutter in tool magazine.
Specific embodiment three：Embodiment is described with reference to Fig.5, on Open Numerical Control System Platform, and utilization is multi-thread
Machining implementation procedure is defined as program main thread by journey programming technique, and intelligent knife-changing system is defined as program sub thread, adds
When work process intelligence tool changing, machining implementation procedure main thread is hung up, and is started simultaneously at execution and is calculated comprising intelligent tool change decision tree
The tool changing sub thread of method, exchanging knives process are finished, and return and continue to execute machining execution program main line at main thread interruption
Journey.
Working principle：Intelligent knife-changing system uses hierarchical structure, and system intelligent decision part is wanted using fusion processing technology
It asks and the decision Tree algorithms model of the knife parameter data set training construction of process tool selection experience, algorithm model is integrated into use
