Quis 1 : Proses Produksi Dan Konstruksi Mesin ( Ppkm ) - Mesin Frais

The correct answer is "ragum mesin." Ragum mesin is a type of machine vise that is used to clamp square workpieces. It is specifically designed to securely hold and grip square-shaped objects during machining operations.

Mesin frais digunakan untuk pemotongan roda gigi. Pemotongan roda gigi adalah salah satu proses pemesinan yang dilakukan menggunakan mesin frais. Mesin frais memiliki kemampuan untuk menghasilkan roda gigi dengan presisi tinggi dan kehalusan permukaan yang baik. Dalam proses ini, mesin frais menggunakan pisau frais khusus yang dirancang untuk membuat gigi pada roda gigi dengan ukuran dan bentuk yang diinginkan. Pemotongan roda gigi merupakan salah satu aplikasi utama mesin frais dalam industri manufaktur.

The correct answer is "rata dan lebar". Pisau frais mantel digunakan untuk pengefraisan alur, rata dan lebar. This means that the mantle end mill is used for milling flat and wide surfaces.

The correct answer is "arbor panjang" because a "pisau frais mantel" (mantel milling cutter) is typically installed on a "arbor panjang" (long arbor) to ensure stability and proper alignment during the milling process. The long arbor provides better support and reduces the risk of vibration or wobbling, which can affect the accuracy and quality of the milling operation.

Pisau frais yang ada di lapangan pada umumnya dioperasikan dengan putar kanan. Ini karena putaran pisau frais secara umum mengikuti arah jarum jam untuk memotong material dengan efektif. Dalam beberapa kasus, pisau frais juga dapat dioperasikan dengan putar kiri tergantung pada jenis material yang sedang diproses atau kebutuhan khusus lainnya. Namun, secara umum, putar kanan adalah metode yang paling umum digunakan dalam pengoperasian pisau frais di lapangan.

A dial indicator is used to set and check the straightness and alignment of the thread on the milling machine table. It is a precision measuring tool that can measure small distances and variations in height or depth. By using a dial indicator, the operator can ensure that the thread is installed correctly and aligned properly, which is crucial for the accuracy and quality of the milling process.

The correct answer is "panjang langkah memanjang" because the length of the longitudinal stroke is one of the measurements that indicate the size of a milling machine. This refers to the distance the milling table can travel in the longitudinal direction. The longer the stroke, the larger the machine's capacity to handle larger workpieces.

The correct answer is "pisau frais alur melingkar". This tool is used to create a closed groove or slot in a workpiece. It has a circular shape and is designed specifically for milling circular grooves. The other options, such as face mill, shell end mill, radius cutter, and dovetail cutter, are not suitable for creating closed grooves.

A slot mill is a type of cutting tool that is used to create slots or grooves in a workpiece. It has a cylindrical shape with multiple teeth or flutes on its cutting edge, allowing it to remove material as it rotates. This type of tool is commonly used in milling operations to create slots, channels, or grooves of various widths and depths. It is different from an end mill, slitting saw, and T slot, which have different shapes and purposes in machining processes. "Alot mill" is not a recognized term in machining.

The correct answer is "pengefraisan gigi yang besar". This is because the plain gear hob is not suitable for machining large teeth. It is mainly used for cutting, grinding, and finishing operations.
