圆锥螺旋线铣削宏程序功能指令开发
|
摘要
针对FANUC 0i-MD数控系统不具备圆锥螺旋线铣削G代码功能指令以及复杂箱体类零件的不同规格的内、外圆锥螺旋线铣削程序编程复杂,加工效率低等问题,文章建立了圆锥螺旋线的数学建模,并运用FANUC 0i-MD系统参数及用户宏程序设计了同一指令并可不同参数赋值的G111代码指令。该指令能够完成不同规格的内、外圆锥螺旋线铣削的粗、精加工。通过在FANUC 0i-MD系统的数控铣床上的模拟仿真和零件试切加工试验,验证了开发的功能指令完全满足圆锥螺旋线铣削加工要求。它具有编程简单、加工工艺广、加工效率高等特点,也进一步扩充了数控系统G代码的功能指令。
Aiming at the problems that the FANUC 0 i-MD system does not have G code function instructions for tapered helix milling, and the inner and outer cone spiral milling programs of different specifications for complex box parts is complex and the processing efficiency is low, this paper studies the parameters of FANUC 0 i-MD NC system and user macro-program, establishes the mathematical analysis and modeling of tapered helix. Furthermore, using the system user macro program, the G111 code instructions with different parameters assigned to the same instruction are developed, which can finish the rough or fine milling of inner and outer conical helix with different specifications. The simulation and part trial-cutting verification on FANUC 0 i-MD NC milling machine prove that the functional instructions developed in this paper fully meet the requirements of conical helix milling. It has the characteristics of simple programming, wide processing technology and high processing efficiency, and further expands the functional instructions of G code of CNC system.
