Description
Technical field
The invention belongs to Jet Polishing technical fields, and in particular to a kind of flexibility cutter automatic tool setting device and method.
Background technique
Jet Polishing technology is a kind of novel optical processing technology developed in recent years, it, which mainly passes through, specially sets
By the liquid directive workpiece containing abrasive grain, the percussion generated using jet impulse workpiece surface and wall surface are flowed the nozzle of meter
The shearing force of generation realizes the removal of material.Jet Polishing, will not in processing due to using liquid as polishing tool
There is tool wear and heat affecting problem, process equipment is simple, and process cleaning, processing flexibility is high, is currently used for solving
Plane, spherical surface, aspherical Ultra-precision Turning problem.
Workpiece coordinate system is established, that is, establishes position of the workpiece coordinate origin with respect to lathe coordinate system, is to realize numerical control programming,
Carry out the prerequisite of automation processing.Existing Jet Polishing lathe is to knife mainly using adjustment and operator's observation repeatedly manually
In conjunction with mode knife since the polishing tool of Jet Polishing is liquid, is deformed immediately when it is contacted with workpiece,
It is big to knife difficulty, low efficiency, the technical level for relying primarily on operator low to knife precision and process experiences, the workpiece that knife is obtained
Coordinate system data consistency is poor.
The self-operated measuring units such as tool setting gauge are configured in current certain high-grade, digitally controlled machine tools, if Zuo Jiasheng is in Chinese equipment work
" design of numerically-controlled machine tool tool auto-checking instrument " that the 12nd phase of journey 2006 delivers, Song Changshuan are in the 5th phase of manufacturing technology and lathe 2011
" application of the tool setting gauge on numerically-controlled machine tool " delivered, machining accuracy and the degree of automation are improved, but are needed for not
Same type machining tool design tool auto-checking instrument, relatively expensive and function is relatively simple, and require by cutter with
Tool setting gauge carries out directly contact and realizes to knife.Other automatic tool preset methods reported at present, as " one kind is based on for the patent of Meng Xianzhang
Perception position to knife measuring head is the numerically-controlled machine tool presetting cutter method of ball " (China Patent Publication No.: CN
103707132A), but it needs to realize using measuring probe and the direct way of contact of cutter to knife, such as the patent of Kunming University
" a kind of numerical control lathe adjusting tool device and presetting cutter method based on machine vision " (China Patent Publication No.: CN 104190963A),
The clear image for needing to shoot cutter to knife is realized using machine vision mode, is then obtained by image procossing to knife data.
But since the cutter of Jet Polishing is liquid, cutter is just formed in the liquid directive workpiece surface containing abrasive grain, and due to
The clear image of cutter can not be obtained by CCD by occurring sputtering when liquid at high speed directive workpiece surface, therefore also not be suitable for penetrating
The flexible cutter of polishing is flowed to knife.
