CNC automatisk programmeringsmetode

Hvor mange metoder er der til NC-bearbejdningsprogrammering?

Automatisk programmering af CNC-bearbejdning
Den automatiske programmering af CNC-bearbejdning kaldes også computerstøttet programmering, det er, det meste eller hele programmeringen udføres af computeren. Såsom at færdiggøre beregningen af ​​koordinatværdier, kompilering af delbehandlingsprocedurer, automatisk udskrivning og udskrivning af behandlingsprocedurer og klargøring af kontrolmedier.

Fræsehjulsbearbejdning af fræsemaskine

Løs deformation af dele i højhastighedsfræsning

Højhastighedsfræsesystemet er et komplekst dynamisk system, som er tilbøjelig til at ryste vibrationer ved bearbejdning af tynde dele. Fladder er en meget stærk relativ vibration mellem værktøjet og emnet under fræseprocessen. Denne form for vibration vil ødelægge den relative korrekte position af værktøjet og emnet, og reducere overfladebehandlingskvaliteten og fræseeffektiviteten. I lang tid, cutting chatter har været et stort forskningsemne i maskinfremstillingsindustrien og fræseforarbejdning.

Ultra-præcision CNC fræsedele

Ultrapræcisionsskæring startede med SPDT-teknologi, som understøttes af luftlejespindler, pneumatiske glider, høj stivhed, højpræcisionsværktøjer, feedback kontrol, og miljøtemperaturkontrol for at opnå overfladeruhed på nanoniveau. Diamantskærere bruges mest, som er meget udbredt i behandlingen af ​​kobber flade og asfæriske optiske elementer, plexiglas, plastprodukter (såsom kameraplastiklinser, kontaktlinser, etc.), keramik og kompositmaterialer.

CNC machining of prismatic parts

Dreje- og fræsebearbejdning af prismatiske dele

The machining center performs multi-process (dreje, fræsning, boring, kedelig, aflytning, etc.) and multi-face composite processing on prismatic parts through automatic tool change and table indexing. Practice has proved that the composite machining center is indeed beneficial to solve the shortcomings of long delivery time, low resource utilization, more products in process and slow capital turnover of small and medium-sized machinery manufacturing enterprises. Turning and milling combined processing has thus gained more and more common applications in industrial production.

What are difficult-to-machine materials?

Difficult-to-machine materials are materials with poor turning and milling workability. Performance of this material is greater than or less indicators (HB> 250, σb> 1000 MPa, δ> 30%, αk> 100 MPa, K <41.8 W / mk) one or more, are all difficult to cut materials. It can also be measured by phenomena in the cutting process (cutting force, cutting heat, tool wear and tool durability, processed surface quality and chip control, etc.).

Problems when cutting difficult-to-machine materials

Cutting is roughly divided into turning, fræsning, and center-tooth-based cutting (end face cutting of drills and end mills, etc.). The cutting heat of these cutting processes has different effects on the cutting edge. Turning is a continuous cutting, the cutting force on the tip does not change significantly, and the cutting heat continuously acts on the cutting edge; Milling is a kind of intermittent cutting, and the milling force is intermittently acting on the tip of the blade, and vibration will occur during milling. The heat effect on the cutting edge is the heating during cutting and the cooling during non-cutting alternately, and the total amount of heat received is less than during turning.

CNC-slibning af præcisionsspejloverflade af legeringsdele

Cemented carbide is prepared by powder metallurgy with tool steel or alloy steel as the binder phase and refractory metal carbides (mainly WC, TiC) as the hard phase. Its structure is characterized by the fine hard phase grains dispersedly distributed in the steel base. The hard phase in the alloy mainly endows the material with high hardness and high wear resistance, and the binder phase in turn endows the material with the properties of steel. Derfor, the steel-bonded cemented carbide has the comprehensive properties of steel and cemented carbide, and it has been widely used in various fields.
