Turning Cut Calculator 3.53

Turning Cut Calculator

The Turning Cut Calculator serves as an efficient tool designed for lathe operators, CNC professionals, and programmers who engage with turning machines. This application allows users to quickly manipulate various turning parameters with ease.

For users seeking additional functionalities, the "Turning Cut Calculator II" app by KenKe offers enhanced features, including calculations for material removal, material removal rate, cutting forces, torque, and power. This advanced version supports multiple languages, provides more extensive help resources, and includes a wider range of customizable settings. Additionally, for milling-specific calculations, users can explore the "Milling Cut Calculator," also developed by KenKe.

Main Features

• Calculates turning cut time based on provided turning data.
• Supports both Metric and Imperial measurement systems with conversion capabilities.
• Allows users to modify diameter, cutting length, cutting speed, spindle speed (rpm), feed per revolution, feed per minute, nose radius, and surface finish (Ra).
• Facilitates conversions between cutting speed and spindle speed, as well as between feed per revolution and feed per minute.
• Estimates Ra surface fineness based on nose radius and feed inputs.
• Provides approximate feed calculations derived from nose radius and specified surface quality.
• Offers absolute input or incremental buttons for fine-tuning parameters.
• Features intuitive switching between input methods through a long tap on the value.
• Updates all relevant values in real-time upon modification.
• Users can customize the duration for highlighting and button visibility.
• Allows selection of highlight colors and button styles for personalized use.
• Saves user preferences and can resume from the last session at startup.

Value Change Events

Modifying a value triggers immediate updates across dependent parameters—referred to as "subvalues" for clarity. Certain values, such as diameter and cutting length, remain unchanged when other values are adjusted. For example, changing surface quality (Ra) will instead alter the feed rate.

The app establishes a hierarchy of priority for value adjustments:

• Cutting Speed (priority)
• Spindle Speed
• Feed per Revolution (priority)
• Feed per Minute
• Nose Radius (priority; unaffected by subvalue changes)
• Surface Finish

This structure implies that subvalues typically adjusted do not hold priority status. Primary values can usually only be affected by subordinate adjustments within each category—excluding nose radius from this rule.

Value Adjustment Implications

• A change in diameter will also alter spindle speed, feed per minute, and total time.
• A change in cutting length affects total time only.
• A change in cutting speed will adjust spindle speed, feed per minute, and time as well.
• A change in spindle speed influences cutting speed, feed per minute, and time accordingly.
• A change in feed per revolution will result in adjustments to feed per minute, surface finish, and time metrics.
• A change in feed per minute similarly adjusts feed per revolution, surface finish, and total time.
• A change in nose radius will modify surface finish alone.
• A change in surface finish will affect feed rates yet not the nose radius.

The main variable is highlighted in a lighter color for prominence, while related subvalues are displayed in darker shades. It is noteworthy that although displayed figures may appear rounded, the underlying calculations maintain higher precision. A detailed guide similar to this overview accompanies the app for user reference.
