CNC machine with 5 Axis



    • how z axis is run on machine with 5 axis (same as 4axis):

0
    • how x axis is run on machine

CNC Makina seçimi

  • Motor tipi ve kalitesi
  • Motor tipi
    • servo motor 
      • yüksek hızda işlemesi
      • her devirde sabit tork
    • step motor = hassas iş
    • spindle motor = düşük hız
  • İşleme alanı
    • Büyük işleme alanı : köprü tipi router
    • Küçük işleme alanı : H tipi yapı
  • Automatic tool charging: kesici uç otomatik değişimi

CNC makina iç yapısı hakkında:
  • kayıt ve kızak tabla hareketi sağlama ve taşıma
  • Fener mili:
    • bilyeli yatak ve vidalar sistemi
    • bu boşluk olmasını engeller
  • Kesici takımların takıldığı magazin, diğer adı palet, takım tutucu
  • Takım değiştirme sistemi
  • Kontrol paneli: veri & program girişi

CNC ile çalışmadan önce

  • kesici ucu xyz sıfır noktasına gönderme
  • iş parçaları doğru bağlamda mı
  • iş parçaları her biri içinreferans 0 noktası ayarlanması
  • İş parçasını tezgah mengenesine bağlama
    • işin kesme kuvvetini karşılamalı
    • parça altı(?) yeterli destek olmalı (sıkı tutturulmuş olmalı ?)
    • hızlı ve kolay sıkılabilmesi/açılması

Important notes to all readers

This page is for my personal use. The photos in it are my copyright, everything else is collected from many websites and forums. I learned these things from all these websites, it was all written notes by hand at 2021. As my notes were getting deteriorated I had to transfer all of them on the internet. 
I am not a pro of CNC, Please refer to pro websites if you want to use these things for educational or pro use.

It is a real good work. It describes the root for the languages. I have found this schema on the internet around 2000. And at this time visual basic did not evolved to something new. but got mixed with C# and all other possible language forming .NET which was really good (under c# this is written).  Second note for this schema, although internet was there (since 70`s?) the sofware related to internet did not really show up, and were not really strong enough in the market. The revolutionising of the internet ability changed this schema radically. While there was few programming language at the 90`s, on 2010 there were I guess more than 100 in the market which were active
