Even though the running speed of motor is set at 3000 RPM (50 Hz), the resonance does not occur since the disturbances during operation has shifted the transient vibrational peak to about 100 Hz with considerable low amplitude of 1.506 m/s 2. From the study, the first sixth modes of the structural have been determined in the range of 0–100 Hz, and the most dominant mode resulted at 54.88 Hz. By using ANSYS v20 software, the RTM structural vibration in terms of modal, frequency response and transient analyses are investigated. The designed RTM using rotational cutting tool can complete the tapping process in faster time with minimum labor contact. In this study, a new concept of intelligent rubber tapping machine (RTM) is introduced as a solution to this problem.

However, the number of skilled rubber tappers are getting lower nowadays, and the available manual tools are unable to cope with the market demand. Due to this, it is necessary to improve the quantity of natural rubber that been produced.

It was found that 30% of the participants had postures that would slightly affect their body, whereas 26% of participants had postures that had to be corrected soon in line with higher action categories. The OWAS was used for carrying out a video-based posture analysis of rubber tappers to study the effects of their postures on the musculoskeletal system and the need for remedial measures. Participants were directly observed while they were working, and their work activity was also videotaped with prior consent. This study was conducted among thirty rubber tappers in Kerala, India, to assess their working postures and evaluate their susceptibility to MSDs. Such a cyclic and monotonous work activity involving numerous ergonomic risk factors exposes rubber tappers to great risks of musculoskeletal disorders (MSDs). Typically, workers tap at least 300 trees in a day, consequently subjecting them to these hazardous postures repeatedly. In performing this operation, workers have to assume awkward postures, including extending of arms, side bending, twisting, flexion and/or extension of the neck, trunk, and wrists.
It is commercially produced by extracting the latex of certain tree species that contain significant amounts of rubber and the process is called rubber tapping. Natural rubber is a vital raw material for modern-day industries.
