DETERMINATION OF LINEAR FORCE OF MICROPOROUS RUBBER CUTTING BY THE KNIFE WITH ONE-SIDED GRINDING
The purpose of this study is to develop a simple and effective evaluation method of the impact the gap between the rollers and the value of the distance from the vertical axis of rollers rotation to the edge of the knife blade have on linear force of microporous rubber cutting by using regression equations. The research has been conducted by the example of the experimental setup of the cutting machine for longitudinal using a knife with one-sided grinding. The application of the rotary plan of the second order during mathematical experiment allowed to efficiently solve the problem of the impact the researched factors have on a linear cutting force. The received results of regression equation describeboth the total value of loss during the longitudinal cut of the material and the value of loss due to material friction on the brink of a motionless knife with one-sided grinding. Comparison of the total value of loss during the longitudinal cut of material by knives of various geometries (with one-sided and double-sided grinding), leads to the conclusion that it is advisable to select the thickness of one-sided blade grindingin the design of machines for splitting and alignment of parts of shoes bottom, which will result indramatic reduction of energy costs.
