Abstract: Low Plasticity Burnishing (LPB) is a state-of-the-art method of surface enhancement, which raises the burnishing to next level of sophistication and that can provide deep, stable surface compression for improved surface integrity characteristics. This paper reports an innovative approach, which was used to design and develop a new LPB tool. The performance of the LPB tool has been assessed on surface roughness and surface microhardness aspects of steels. This type of design has certain inherent advantages in terms of flexibility in controlling the process. Low cold work, better finish, improved surface hardness, enhanced fatigue life, corrosion resistance, improved dimensional control, etc., are some of the all-round benefits that can be obtained from the current apparatus. This technology could be very useful, ranged from common small-scale industries to hi-tech applications, as the tooling and fixturing were developed with a vision to process varieties of materials for versatile applications and the process can be readily accommodated in an existing machine shop environment. The process could be applied to critical components effectively, as it has significant process cycle time advantage, lower capital cost and suitability to adapt existing machine layout and high-speed machining concepts.
