Abstract
An intelligent Tool System used with Computer Numerical Controlled machining centers consisting of a method of establishing tool presence and type of tooling device and a method of eliminating any error due to thermal growth. The spindle mechanism provides CNC Communicating and Operating means with spindle mounted devices for establishing tool presence and type of tooling for eliminating error due to thermal growth and for determining the function of tooling devices such as telescoping tool holders for determining work surface location with random length tools and for sensing tool condition; automatic boring tools for high precision boring and contouring; probing devices for work surface location, measurement and definition; combination boring and probing tools for boring and measuring a hole without removing the tool from the spindle.
