Study on the Chip-excluding (1st Report)

An estimating method of the facility of chip-excluding is proposed, and this method is applied to the case of chip-absorbing with air. The following results are obtained from this study : (1) The facility of chip-absorbing with air (time necessary for absorbing a unit volume of chip or the ratio between the weight of absorbed chip and that of total produced chip) is estimated quantitatively by the following “shape coefficient of chip CR” which consists of terms of the maximum length of a chip L (mm), the weight of a chip W (g) and the volumetric coefficient RCR= L+ 17.47 W+4.18 R(2) The capacity of chip-excluding machine, suitability of cutting conditions, etc. can be quantitatively estimated by “shape coefficient of chip CR.”
