Abstract
Dalam industri manufaktur, mesin freis merupakan mesin perkakas yang digunakan untuk menghasilkan produk dengan ketelitian dimensi dan kualitas permukaan yang tinggi. Akurasi hasil pemesinan dipengaruhi oleh kondisi geometris mesin, terutama worktable. Seiring penggunaan, worktable dapat mengalami penyimpangan geometris akibat keausan pada permukaan meja dan guideway. Penelitian ini bertujuan menganalisis akurasi geometris worktable mesin freis vertikal WELLS INDEX 847 berdasarkan parameter kesejajaran dan ketegaklurusan menurut standar ISO 1701. Pengujian dilakukan pada parameter G5(A), G5(B), G6(A), G6(B), G7(A), dan G7(B) menggunakan dial indicator dengan lima kali pengulangan pada setiap titik pengukuran. Data dianalisis menggunakan uji normalitas Ryan-Joiner, uji homogenitas Levene, ANOVA, uji Tukey, dan Total Indicator Reading (TIR). Hasil penelitian menunjukkan bahwa pada parameter G5(A) diperoleh nilai TIR sebesar 0,019 mm pada bagian tengah permukaan meja, 0,037 mm pada bagian kanan, dan 0,045 mm pada bagian kiri. Pada parameter G5(B), G6(A), G6(B), G7(A), dan G7(B) masing-masing diperoleh nilai TIR sebesar 0,029 mm, 0,166 mm, 0,141 mm, 0,182 mm, dan 0,142 mm. Berdasarkan batas toleransi ISO 1701 sebesar 0,025 mm, hanya parameter G5(A) bagian tengah yang memenuhi batas toleransi, sedangkan parameter lainnya berada di luar batas toleransi. Hasil tersebut menunjukkan bahwa akurasi geometris worktable mesin freis vertikal WELLS INDEX 847 telah mengalami penurunan akibat keausan pada permukaan meja, guideway, dan komponen penuntun gerak sehingga diperlukan evaluasi kondisi geometris serta tindakan perawatan maupun penyetelan untuk mengembalikan akurasi mesin.

In the manufacturing industry, milling machines are widely used to produce components with high dimensional accuracy and surface quality. Machining accuracy is influenced by the geometric condition of the machine, particularly the worktable. Over prolonged use, the worktable may experience geometric deviations due to wear on the table surface and guideways. Therefore, this study aims to analyze the geometric accuracy of the worktable of a WELLS INDEX 847 vertical milling machine based on the parallelism and squareness parameters specified in ISO 1701. The measurements were conducted on parameters G5(A), G5(B), G6(A), G6(B), G7(A), and G7(B) using a dial indicator with five repetitions at each measurement point. The data were analyzed using the Ryan-Joiner normality test, Levene’s homogeneity test, Analysis of Variance (ANOVA), Tukey’s test, and Total Indicator Reading (TIR). The results showed that the G5(A) parameter produced TIR values of 0.019 mm at the center of the worktable, 0.037 mm on the right side, and 0.045 mm on the left side. The TIR values for G5(B), G6(A), G6(B), G7(A), and G7(B) were 0.029 mm, 0.166 mm, 0.141 mm, 0.182 mm, and 0.142 mm, respectively. Based on the ISO 1701 tolerance limit of 0.025 mm, only the center section of the G5(A) parameter satisfied the specified tolerance, while all other parameters exceeded the allowable limit. These findings indicate that the geometric accuracy of the worktable of the WELLS INDEX 847 vertical milling machine has deteriorated due to wear on the table surface, guideways, and guide components. Therefore, geometric condition evaluation, maintenance, and machine adjustment are required to restore the machine's geometric accuracy.
