Abstract:
Because of the combination of self-made or common boring bar and CNC program, we machined two external cylinders used for tightening ring (φ500u6(+0.58/+0.54)×130mm ) of a vertical roller mill, and conquered the difficulty on machining high-precision cylindrical on the boring machine. This process improvement not only brings the machining advantage of CNC machine tools into full play, but also organically integrates conventional boring to turning methods, which can cause high machining efficiency. Since the special tooling is not needed and it’s easy to obtain materials from local sources, we

Vibration speeds of oscillations in the direction of coordinate axes with the aid of which one defines actually amplitudes of deformations are defined. As a result of investigations there are determined dependences to obtain amplitudes of deformations, mean-square values of oscillation speeds affecting errors at parts machining on boring lathes.

Abstract Considering the background of the Shanghai Jing’an Smart Garage Project, first, we introduced the world’s largest vertical shaft boring machine, which was suitable for vertical shaft excavation of diameter 12∼23 m. Then, we expounded the design points and key technologies of super large and deep diameter assembly shafts in soft soil layers. Finally, we verified the applicability of the vertical shaft boring technology in soft soil layers in Shanghai through on-site measurement results. It was observed that this technology had a minimal impact on the surrounding environment, indicating

Turning (boring) was considered as an example, and a number of measures aimed at improving the quality of the surface at the design stage were also proposed. A simulation stochastic model of surface roughness shaping during surface turning was proposed. Based on this model, an algorithm and a computer program were developed to calculate the roughness at the design stage. The initial data for modeling are the main angle

Abstract Internal turning process is a very important and widely used process for enlarging and finishing holes.

In that case, the correct definition of working parameters will directly contribute to the quality of component. Aim of the current research was to analyse the form error and the roughness of workpieces submitted to internal turning process using boring bars in long overhangs with three different internal tools (steel, carbide and antivibrating tool).

Abstract:
Achieving high workpiece accuracy is a long-term goal of machine tool designers. Many causes can explain workpiece inaccuracy, with thermal errors being the most dominant. Indirect compensation (using predictive models) is a promising thermal error reduction strategy that does not increase machine tool costs. A modeling approach using transfer functions (i.e., a dynamic method with a physical basis) has the potential to deal with this issue. The method does not require any intervention into the machine tool structure, uses a minimum of additional gauges, and its modeling and calculation speed
