“…Based on the evidence presented, it is, however, arguable that neither paper-based nor electronic information is a CNC machinist's primary source of reference. Instead, tacit or experiential knowledge is what a machinist refers to first (Böhle et al, 1994;Hazlehurst, Bradbury, & Corlett, 1969;Kasvi et al, 1996;Taylor, 1978;Tuominen et al, 1989). Information is merely a supplementary form of support when the machinist cannot recall detail (Kasvi et al, 1996).…”

As information technology (IT) capabilities increase, manufacturing businesses are realigning their information systems infrastructure to remain competitive. This has resulted in substantial increases in IT use in technical areas of the business. Nevertheless, conventional paper-based information systems are still common at the shop floor. Hence, manufacturers need to understand whether there is benefit in extending IT functionality to the shop floor. By evaluating the impact of hypermedia information systems on the independent decision-making and communication capabilities of computer numerical control (CNC) machinists, this research aims to identify the shop floor benefits of replacing existing paper-based systems with this relatively new technology in this context. The research findings have wide-ranging implications for further research into the strategic implementation of shop floor IT and for future work structures in the metal cutting industry.

“…The reviewed literature does not distinguish between the information requirements for CNC planning (i.e., programming) and execution tasks (Sauer et al, 2000;Taylor, 1978). In a skill-based environment, shop floor programming is stated as a core competence (Schultz-Wild, 1993).…”

The product quality of hard steel material formed by a shaping machine using HSS tools was studied under the influence of machining variables. The research focused on the effects of tool vibration on the surface roughness of the product. The experimental process was carried out by selecting the machining independent variables, namely: cutting speed (V) = 1 m/min; 2 m/min; 3 m/min; cutting thickness (a) = 1 mm, 1.5 mm, 2 mm; feeding motion (f) = 5 mm/step; 8mm/step; 10 mm/step. Shaping machine was operated with 3 fixed speed levels (n) of 21.8 rpm, 39 rpm and 59.8 rpm, respectively. The dependent variable, namely stroke per minute (np); and feed rate (Vf). The material used was ASTM A483-A high carbon steel. Vibration measurements were taken during machining using an ADXL 345 accelerometer and an Arduino Pro Mini with support for Arduino IDE 1.8.13 and USB TTL CP 2120 software. Vibration acceleration (af) on the tool was recorded and an evaluation was performed to determine the effects of machining variables on the final products. The results show that speed lavel of machine, feed rate , and cutting thickness majorly affect vibration. The lowest vibration was obtained at a speed (n) of 21.8 rpm, a feed rate (Vf) of 1 mm/s, and cutting thickness (a) of 0.2 mm. The highest vibration was obtained at n of 59.6 rpm, Vf = 1 mm/s and a of 0.4 mm. The quality of the product related to the surface roughness was mainly influenced by the machine speed levels. The roughness values ranged from 3.97 to 6.46 µm, with the lowest surface roughness or smoother surface achieved at a moderate speed of 39 rpm and higher surface roughness at high (59.8 rpm) and low (21.8 rpm) speeds.
