EXAMINING THE RELATIONSHIP BETWEEN DISTORTION CHANGES IN HEAT-TREATED SHAFTS AND STRAIGHTENING FORCE
 
Shafts produced in the machining sector must be heat treated to provide the required hardness values. Due to the high temperature applied to the shafts during heat treatment, distortion changes occur in the shafts, causing the part to fall outside the desired tolerances. If the part is out of tolerance, it prevents its use in the desired place and its intended purpose. Size and shape changes caused by heat treatment have long been the subject of scientific and industrial research. Tolerances in mechanical parts working together are very important in terms of both function and cost. Especially in mechanical parts produced by machining, narrow definition of tolerance ranges significantly increases costs. For this reason, it is desirable that mechanical parts working together can be assembled and produced with the widest possible tolerances. Heat treatment of mechanical parts and tools, in addition to the usual task of ensuring highly complex mechanical and operating properties, also involves the deformation of the product during the heat treatment process and the need for control operations (performed manually). In order to bring the shafts that are out of tolerance into tolerance, a bending/compressing force is applied to the shaft, and this bending/compressing force varies depending on the magnitude of the deflection in the shaft. Within the scope of the study, bending/compressive force and deformation rates and the changes of these rates according to material, heat treatment and bending/compressive force will be examined.
