Abstract: The article discusses the effect of riveting on the required shape accuracy (flatness) of thin long parts made of 08H15N5D2T steel during sequential machining. Flatness is a parameter of shape accuracy, which is characterized by the degree of deviation of the surface from a perfectly flat state relative to an ideal body (an ideal body means a body that has a certain degree of shape accuracy, confirmed by special techniques). It is affected by mechanical processing and the ability of the metal to store the received energy in the form of stresses. The machining modes, if selected incorrectly, introduce greater hardness into the product layers compared to the hardness obtained after heat treatment. This phenomenon is called riveting (or over-riveting). Heat treatment also plays an important role in obtaining the required accuracy values. With a rationally selected heat treatment mode, the amount of riveting decreases with the same machining modes, as well as the likelihood of over-riveting. The article conducts experiments on 08H15N5D2T steel samples and presents the cutting modes used in production for end milling and flat pendulum grinding of manufactured parts, as well as their effect on flatness under various pre-heat treatment modes. Conclusions are drawn based on the results obtained.
