- As experimental conditions, the process variables including number of rotations, number of tool teeth, and cutting direction were varied to perform 36 tests or hole-shaped specimen processing, as well as 36 tests for shaft-shaped specimen processing.
- depth of cut by each worker. For these purposes, this study has intentionally generated the shape of the whole and shaft run-out at the AL6061 base material, which is most commonly used for weight reduction in the aerospace, robotics, high-tech parts, and semiconductor equipment parts industries, under the conditions of the same process variables, the number of rotations, the number of tool teeth, and cutting direction at the same depth of finishing cut and processing, in order to investigate the correlation between roundness, cylindricalness, and surface roughness in quality characteristics.
- Measurement was performed with an indicator, and the run-out amounts were set to 0.007 mm, 0.040 mm, and 0.070 mm, respectively. The rotational speed (RPM) of the spindle was set in the low-speed (3, 000), medium-speed (6, 000), and high-speed (12,000) modes.
- The specimen was fixed by using the Samchully Power Vice PCV-160 model to prevent any problem in the quality characteristics due to the clamping force, and the test was performed by setting it to stage 0.
