Description

(54) METHOD OF GRINDING

one.

The invention relates to mechanical engineering and can be applied in the processing of parts on grinding machines.

There is a known method of grinding, according to which the removal of the main allowance is carried out at a constant cross feed of the grinding wheel, after which the part is machined without cross feed 1.

This grinding method is inefficient due to the length of the final processing period.

There is also known a method of grinding, which includes plunging, the period of steady removal of the allowance and accelerated nursing during the reverse feeding of the grinding wheel

However, this method does not provide high precision machining of parts, as due to the rapid unloading of the AIDS system, inaccuracies in the workpiece are not completely eliminated.

The purpose of the invention is to improve the accuracy of processing details.

This goal is achieved by the fact that the initial period of nursing is chosen equal to 0.1-0.3 nursing time.

while drying: force is applied to the part perpendicularly directed, the axis of rotation of the grinding wheel is an effort whose value is equal to the difference between the normal component cutting force in

5 the end of the period of the steady removal of the allowance and the current normal component of the cutting force during nursing without force on the part.

FIG. 1 shows a schematic diagram, illustrating) 0 the treatment process at the nursing stage; in fig. 2 - graphically grinding cycles: 1 - by the proposed method, 2 - by the known.

The proposed method of grinding involves plunging the grinding wheel 1 into detal 2 for a period of time t, a period of steady removal of the allowance for a period of time T2I, when the grinding wheel 1 is fed back from part 2, and during the period of time t per part, force is applied R directed in the direction of the grinding wheel perpendicular to the axis of its rotation, the value of which is equal to the difference between the normal component R of the cutting force at the end of

Claims (1)

Claim The method of grinding, which includes plunging, the period of steady removal of allowance and accelerated nursing during the return feed of the grinding wheel, characterized in that, in order to improve the accuracy of machining the part, the initial nursing period is chosen equal to 0.1—0.3 nursing time the impact on the part is directed perpendicular to the axis of rotation of the grinding wheel force, the value of which is equal to the difference between the normal component of the cutting force at the end of the period of the established removal of allowance and current the normal component of the cutting force when nursing without force on the part.
