A conventional manual lathe electric motor drives the multi-stage gearbox transmitting torque to the spindle so that the workpiece makes contact with the machine tool at a given speed. The cutting speed is proportional to both the diameter of the workpiece and the spindle speed, however, the increments in spindle speed are limited. Manual lathe machines cannot be regulated at the optimum cutting speeds for all diameters.

Abstract:

Thermal error is one of the main reasons for the loss of accuracy in lathe machining. In this study, a thermal deformation compensation model is presented that can reduce the influence of spindle thermal error on machining accuracy. The method used involves the collection of temperature data from the front and rear spindle bearings by means of embedded sensors in the bearing housings. Room temperature data were also collected as well as the thermal elongation of the main shaft. The data were used in a linear regression model to establish a robust model with strong predictive capability. Three

Abstract:

The selection of turning speed is very important because the turning process affects the quality of the work, especially in the metal industry and small or medium-sized industries. To meet production needs, the rotational speed of the lathe can be adjusted to various spindle speed levels. Variations in speed will cause the workpiece to differ in terms of flatness and smoothness. The turning process begins with a linear motion along the axis of the AISI 1040 steel workpiece, with a slow feed of 2 mm. Smooth and even results were obtained at speeds of 80 rpm, 105 rpm, 160 rpm, 250 rpm, 380 rpm,
