Understanding Investment Casting

Milling involves the use of rotary cutters to remove material from a workpiece. Unlike turning, where the workpiece is rotated, milling machines hold the workpiece stationary and move the cutting tool across its surface. This process allows for the creation of complex shapes, slots, and holes. Milling can be categorized into two main types vertical milling and horizontal milling, depending on the orientation of the cutting tool. It is widely used in the manufacturing of molds, fixtures, and intricate mechanical components.

4. Overhead Costs These are indirect costs associated with the manufacturing process, such as utilities, maintenance, and administrative expenses. Allocating overhead costs accurately is critical to ensure that the costing sheet provides a realistic picture of overall expenses.

3. High Accuracy The process ensures high-dimensional accuracy and excellent surface finish. This high level of precision is crucial in industries like aerospace, where even a minuscule defect could lead to catastrophic failures.
