[ABSTRAK
Permintaan akan produk-produk mikro yang sedang meningkat pesat dewasa ini
menyebabkan proses manufaktur cetakan mikro mendapat perhatian dan
penekanan lebih, guna mendapatkan pemahaman yang semakin mendalam untuk
mencapai hasil akhir produk mikro yang semakin berkualitas [1-4]. Proses micromilling
merupakan proses yang populer dalam memanufaktur cetakan mikro
karena kapabilitas dan fleksibilitas yang dimilikinya terkait proses pelepasan
material terhadap benda kerja [1-3,5-7]. Proses manufaktur cetakan mikro dengan
material steel ST41 dan alumunium AA 1100 berukuran 3 x 3 x 3 mm yang
dilakukan dalam penelitian ini menggunakan proses pemesinan milling 3 axis
terhadap kontur sculptured surface dan logo android dengan cutting tool
berdiameter 0.1 mm sampai ukuran 2 mm.
Lintasan pahat yang dibuat telah menghasilkan permukaan produk dengan profil
yang dikehendaki. Dilakukan pengambilan gambar SEM pada hasil pemesinan
cetakan mikro ini, serta dilakukan analisis mengenai dua pola lintasan pahat yang
dibuat dengan menggunakan software CAM untuk operasi roughing yang
dikerjakan yaitu metode face milling (planar) dan cavity milling (contour) yang
hasilnya menunjukkan bahwa metode cavity mill memerlukan machining time
yang lebih singkat. Analisis dari perbandingan jumlah CL point yang terdapat
pada bagian lintasan pahat yang serupa antara produk makro dan produk mikro
juga dilakukan dan didapatkan bahwa densitas CL point pada lintasan pahat
produk makro lebih besar dibandingkan yang dimiliki lintasan pahat produk
mikro.;
ABSTRACT
The increasing demand of micro products these days causes the manufacturing
process of micro-molds gets more emphasis and attention in order to gain better
quality of micro-products [1-4]. The micro milling process is popular as the
chosen method to manufacture micro molds due to its capability and flexibility in
machining operation [1-3,5-7]. In this research, the manufacturing processes of
micro molds of 3 mm x 3 mm x 3 mm from steel ST41 and alumunium AA 1100
were carried out using 3 axis micro milling utilizes various cutting tools from 2
mm diameter to 0.1 mm of diameter. The designed tool path successfully
produced the specified profile of the machined surface.
SEM photographs were taken to observe the machined surface and an analysis of
two tool path generation methods of face milling area (planar) and cavity mill
(contour) using CAM software was conducted and shorter cutting time for the
cavity milling method was found as the result. Analysis of CL point density
comparison between the micro molds and macro molds roughing tool path in the
same region was also done with the comparable applied cutting parameters and
the result shows that the macro mold roughing tool path has denser CL point than
the other of the micro mold?s., The increasing demand of micro products these days causes the manufacturing
