CNC programozás.
A Computer Numerical Control (CNC) olyan szerszámgép, amely programozható mikroszámítógépet is tartalmaz, ami a vezérlését végzi. Megalkotását a kézi megmunkálás igen jelentős mellékidő szükséglete, azaz a termelékenység növekedése, valamint a nagyságrendekkel jobb ismétlési és pozicionálási pontossága tette szükségessé, mert az előkészítés (például berajzolás) és az egyes műveletek közötti szerszámváltás, fogásvétel, fokozatkapcsolás jelentős időt vesz igénybe, ami összemérhető a megmunkálás főidejével. A számítógépek alkalmazása lehetővé teszi az egyidejűleg több tengely mentén végzett és nem egyenes menti mozgásokat is, ami kézzel lehetetlen. Vezérlését alapvetően a beépített mikroszámítógép programozása, működését a felépítmény, azaz a vezérelt gép és az alkalmazott technológia határozza meg. CNC programozás
CNC programozás
A CNC gépeket 2 és 2,5 tengely esetén lehet egyszerűbb geometriai alakzat esetén gazdaságosan kézzel programozni. A 3 vagy 3+ tengely eserén kizárólga CAD – CAM programok felhasználásával valósítható meg a programozás. CNC programozás
CNC programozás – eszterga jellegzetes pontjai
A CNC eszterga (marógépnek is) jellegzetes pontjai vannak melyet a programozásnál, a munkadarab elhelyezésénél figyelembe kell venni. CNC programozás
Abszolút méretmegadás
A CNC programozásnál a munkadarab nulla pontjához javasolt megadni az összes méretet, amit abszolút méretmegadásnak neveznek. Ilyenkor mindig lehet tudni, hogy a nulla ponthoz képest mekkora a távolság a relatív méret megadáshoz képest, mely mindig az előző megmunkálási ponthoz van értelmezve. CNC programozás
A kézi programozás az un. ISO G kódban történik. Minden sorban kell lenni egy vagy tobb párhozamos végrehajtható utasításnak, tengely méreteknek, beállításoknak, stb. A program szintaktikája nagyon egyszerű, jellemzően egy irányba haladó, ritkán alprogramot (ciklust) használ a megmunkálás amit a hagyományos gyártás technológia alapján részerke kell bontani (nagyolás, simítás, menet készítés, stb.).
