The paper presents analytic model of the cutting velocity model of multiple disc milling. To determine the equation of the particle's relative motion in the inter-disc space i.e. dependence between its distance x from the axis of rotation and time t , the forces acting for a single piece were defined: gravity force, horizontal component reaction of the milled material, vertical component reaction of the disc surfaces, fictitious internal centrifugal force, and fictitious Coriolis force. The new developed model gives accounts the following features and phenomena characteristic of milling: tool eccentricity, insert throw, uneven insert spacing, spindle tilt – either steady or variable, spindle error motion, changes in the effective disc geometry due to machining parameters, type of operation (up- or down-milling) and spindle tilt.
