| Summary: | CNC machine tools have two main characteristics in order to produce a product
with high accuracy, including the accuracy and precision of each component of the
machine tool. However, the accuracy and precision of CNC machine tools can be reduced
due to several factors. One of the factors that influence accuracy and precision is geometric
errors.
The geometric errors found in the VMC 500 CNC machine tools originate from the
ball screw and linear guideway components, where the geometric errors reviewed in this
study only consist of straightness errors and angular errors. The deviation value obtained
based on the measurement results from the research conducted by Komang Bagiasna and
Darto, will be compared with the tolerance value based on ISO 10791-2: 2001 standard in
accordance with the respective test codes.
The repair method used to draft a repairment procedure for geometric errors on a
VMC 500 machine is the rebuild method. The repair process carried out by the rebuilding
method includes the leveling and alignment process, dismantling the X-axis drive subassembly,
hand scraping, reassembling the axle drive sub-assembly, and testing the X-axis
movement. |
