Ultrasonic precision optical grinding technology

Ultrasonic machining of optical and ceramic materials

“…In previous testing, OptiSonic has demonstrated its ability to reduce the forces by up to 50% [3]. With that reduction in force, feed rates and depths of cuts can now be pushed to for faster processing times.…”

Designing optimal automatic cycles of round grinding based on the synthesis of digital twin technologies and dynamic programming method

“…The control parameters and the relationship with the cutting parameters with the productivity of the operation and the quality of the surface to be treated have been studied by Malkin (1981), Fang et al (2016), Raoufinia et al (2019). As follows from these works, as well as the works of Uhlmann et al (2016), Pereira et al (2009), Liu et al (2017) and Rowe and Ebbrell (2004), programming the flow parameters of the feed loop is a difficult task, because it is necessary to set the number of stages of the cycle, the feed amount at each stage of the cycle, and the distribution of the allowance along the cycle steps.…”

“…A literature review surveys books, scientific articles and other sources of relevant information, is refers to many scientists have been engaged in studying the theory of designing optimal grinding cycles for CNC machines of operational performance management, when designing an operation for a CNC machine, the greatest difficulties occur at the stage when the technologist assigns cutting modes and projects a feed switching cycle, depending on the remaining part of the allowance. In the process of designing the grinding operation, the technologist should strive to de-sign optimal cycle parameters that will ensure the maximum productivity of machining the batch of parts, taking into account the following technological factors and requirements noted in the works of Cahill et al (2015), Lur'e (1979, , Amitay et al (1989), Phan et al (2011), Pereverzev and Akintseva (2015), Akintseva and Pereverzev (2017), Alagumurthi et al (2007), Lee et al (2006), Krajnik et al (2008), Bertsekas (1995), Lee (2008), Nishimura et al (1989), and Hashimoto and Lahoti (2004). However, none of the papers considers the improvement of the design quality of the optimum grinding cycles in terms of their resistance to variable processing conditions existing in real circular grinding operations performed on CNC machines.…”
