The invention relates to mechanical engineering and can be used in the combined preliminary and final processing of multifaceted parts.

The aim of the invention is to expand the technological capabilities of machining parts with flat and curved surfaces by processing multifaceted parts with flat and curved surfaces sequentially in several machining areas in a single installation.

The processing method is. that each detail is reported by translational nepeMeinetnie but circumferences of grinding and polishing abrasive tools, such as circles, which rotate with working speed, and, at some positions, additional translational motion along a trajectory lying in a plane perpendicular to the plane of translational movement along a circle and directed below right or sharp angle to the working surface abrasive1 o tool.

To ensure a rational speed of interchanging the detail, its value is set directly proportional to the angle of the translational movement around the circumference within which the surface of the part is processed, and inversely proportional to the processing time and the value of the central angle formed by the rays of the translational trajectory details, describe |) ak) - tsimis on the arc, which is the line of instant contact of the part with the paooneii surface of the abrasive tool.

Processing is carried out in the following manner.

A few details, evenly spaced, but a circle having a radius equal to the radius of the translational trajectory, move from position to position. In this case, the processing of | t, 1px turning surfaces of the first parts is carried out due to the contact with the flat working surface of abrasive tools. The position of workers in the chiropy of abrasive and manual tools can be myooplastic and depends on the shape of the parts.

At the 1 st position, processing of curved surfaces of parts is necessary; they are informed by additional translational motion of the trajectory lying in the plane, perpendicular to the plane of the continuous movement around the circumference, and directed under the straight line or sharp m corner. uma to the working surface of the abrasive tool, which may be cylindrical or thin. Due to this, the movement of the workpiece relative to the abrasive tool is ensured in the process of moving around the circumference.

The speed of moving parts can be uniform, however, it is advisable to set it on a right proportional to the angle corresponding to moving the part around the circumference, within which the surface of the part is processed, and inversely proportional to the processing time and the central angle formed by the rays equal to the radius of curvature the actual path of the translational movement and resting on the ends of the arc., which is the line of instant contact of the part with the working surface of the abrasive tool cient.

In this way, due to the complex translational movement of the parts, folding out of the displacement around the circumference and along the trajectory directed at an angle to the working surface of the abrasive tool, the possibility of successive machining (ki of both flat and curved surfaces .MPO1 of the faceted parts is achieved, significantly expands the technological capabilities of the proposed method.
