Abstract:

Purpose. To create a method for using a new indicator of the intensity of cutting modes which will reduce the amount of reference information on the methods of both grinding and machining with a blade tool.

Methodology. Analytical research.

Findings. A new local indicator of the intensity of cutting modes, which has a clear physical meaning – the thickness of the cut – is proposed. It is determined by the projection of the feed rate of the part in the direction of the normal to the surface of the tool. The indicator can be applied to various kinematics of processes of grinding of details. The technique is suitable for abrasive and blade tools. Thanks to the new indicator, the amount of reference information is reduced.

Originality. As an indicator of processing intensity instead of the integrated indicator of specific productivity it is offered to use the local one – a projection of speed of relative movement of giving in the normal direction. The indicator has a clear physical meaning and determines the thickness of the cut for a given cutting speed. It allows considering all kinematic components and contains the full information on loading of a site of a profile within contact, allows distinguishing passing and counter processing which depend on a mutual direction of vectors of speed of cutting and circular giving. The relationship between the projection of the relative velocity in the normal direction, the specific productivity and the length of contact is found.

Practical value. The indicator of grinding efficiency modes for methods of longitudinal and expressive machining of parts is determined. It gives an opportunity to unify the data of tables of modes, to use calculations both for various methods for grinding, and processing by the blade tool. A method for determining the grinding efficiency index with an oriented tool, where stability acts as an objective function, is proposed. Productivity is a balance condition, and surface roughness determines the boundary condition. The definition of extreme values of intensity is given. Separate indicators of the mode both for the created new technique and the one used on the equipment of the known German firm are defined.
