Abstract

Proses bending adalah proses deformasi secara plastik dari logam terhadap sumbu linier dengan hanya sedikit atau hampir tidak mengalami perubahan luas permukaan dengan pembentukan pelat lembaran melalui tekanan punch dan die pembentuk. Pada proses bending, pembuatan punch dan die yang baik bertujuan untuk menghindari springback yang terlalu basar. Tujuan penelitian ini adalah untuk menganalisis pengaruh variasi punch dan die pada proses bending pelat stainless steel tebal 1 mm . Teknik pengumpulan data menggunakan alat press tool laboratorium. Variasi sudut punch yang digunakan adalah 80°, 85°, dan 90° dengan sudut target bending adalah 90°. Variasi radius punch yang digunakan adalah 2 mm, 4 mm, dan 6 mm. Sedangkan sudut die yang digunakan tetap yaitu 90°. Spesimen stainless steel memiliki dimensi 100 x 50 mm dengan ketebalan 1 mm.. Spesimen stainless steel memiliki dimensi 100 x 50 mm dengan ketebalan 1 mm. Dari penelitian ini dapat disimpulkan bahwa semakin besar sudut punch maka semakin besar pula sudut springback yang dihasilkan pada ketebalan pelat stainless steel 1 mm. Semakin besar radius punch maka semakin besar pula springback yang dihasilkan.

Abstract

CNC machines allow computer programming to control the movement and actions of the machine, enabling more precise and repeatable production. However, in operating a CNC machine, good and efficient programming is essential. To optimize the use of CNC machines, it is necessary to optimize the number of NC program blocks that include the concept of macros and sub-programs. An effective CNC program, along with the proper use of macros and sub-programs, can speed up the production process, reduce human error, and increase accuracy. The research method used is comparative research by comparing using macro programs and manual programming, in this case comparing the number of solid trajectories and the number of program lines in the design using the simulation method using the Autodesk Fusion 360 application. So that the optimal number of movements will be obtained through the row value in the NC program. Macros and sub- programs allow users to easily change or modify CNC programs without having to rewrite the entire program. This increases flexibility in producing various types of products. It is concluded that optimization using macro and sub-programs provides a significant reduction in the number of program blocks in the case of the machining process for manufacturing the cover of pressure cylinder. This reduction in program blocks can help improve efficiency and sustainability in the development of modified machining processes.
