Determining the required gripping force of a power chuck Power-operated clamping devices A Turning I) Calculating the required gripping force Fspz The gripping force required depends on the Type of work to be performed. The cutting force on the turning tool has three basic components: Main cutting force Fs - feeding force Fv - passive force (static force) Fp. During turning, the feeding force Fv and the passive force (static force) Fp are mainly absorbed by the jaw faces in contact with the seated workpiece. The remaining main cutting force produces a moment (Fs x dz/2) which must be absorbed by the chuck and transmitted by friction at the clamping point. The moment produced by the main cutting force during turning determines the gripping force required: Fs . S z sp F spz = (1) dz d sp . where: Fspz = gripping force required for a specific job with the chuck stationary = main cutting force Fs chucking ratio dz = dsp μsp Sz machining diameter chucking = cucking coefficient (friction between jaw and workpiece) = safety factor The feeding force and passive components, Fv and Fp, are not included in this formula. If necessary for extreme conditions, they are included in the safety factor Sz. Power-operated clamping devices The main cutting force Fs is calculated from feed, depth of cut and material. where: s= feed, mm/rev. t= depth of cut, mm kc = specific cutting force, kN/mm2 Fs (2) = s . t . kc The product s x t (feed.depth of cut) = chip cross-section (can be obtained from Table 1).
