A tool used to determine the angular change of a conical shape over a linear distance, this device simplifies the process of calculating the degree of inclination. For example, if a cylindrical object needs to reduce in diameter by a certain amount for every foot of its length, this instrument provides the precise angle required to achieve that reduction. It is typically expressed in units of degrees or minutes.
Accuracy and efficiency in machining, woodworking, and other manufacturing processes are greatly enhanced through its utilization. Historically, such calculations were performed manually using trigonometric functions, a time-consuming and error-prone process. The device eliminates these issues, leading to improved product quality, reduced material waste, and streamlined workflows. This is particularly beneficial in large-scale production environments where even small inaccuracies can accumulate into significant problems.
