유니버셜 헤드의 오차분석 소프트웨어 개발

Machining center including Universal head is very useful for the complex shape workpiece. It is composed of upper head and lower head to make various tool angle. But the universal head is installed with 2.5 degree index motor because of machining stiffness Therefore there is tool position error compared with wanted angle. Error analysis software was developed to analyze tool position error of universal head with workpiece compensation angle.
