MAIN PROPERTIES

- Calculates the time for a lathe cut by using given cutting data
- Calculation of input data also gives values for surface finish, material removal, chip thicknesses, cutting forces, torque and power
- Possible process-data that can be changed are diameter, cutting length, cutting speed, spindle speed, feed per revolution, feed per minute, tip radius, surface fineness, processing type, cutting depth, entering angle, rake angle, material, specific cutting force (kc) and efficiency
- Handles both of the systems Metric and Imperial
- Possible to convert between these two systems
- Converts between cutting speed and spindle speed
- Converts between feed per revolution and feed per minute
- Calculates an approximate surface quality from given tip radius and feed
- Calculates an approximate feed from given tip radius and surface quality
- Calculates material removal and material removal rate
- Calculates maximum and average (equivalent) chip thicknesses
- Obtain a good "Specific Cutting Force" via material selection
- Calculates approximate cutting forces
- Calculates approximate torque and power
- Almost all values can be changed by entering absolute value or with buttons for step change
- Required updates of affected values occur immediately
- Switching between change methods is made by a long tap on the value's row
- Possibility to get a short explanation about a value with a fast double tap on the value's row
- Possibility to get explanations of other result values with a quick double-tap in the specific result area
- Ability to select time for viewing highlighted text and active buttons
- Ability to select color theme
- Ability to adjust color tones for the color themes
- Possible to select main font
- Possibility to change the appearance of highlighted sub-values
- Possible to create new default values
- All settings are stored for the next use of the app
- Possible to continue with the last session when starting the app


HANDLING IN BRIEF

At the start of the app, all properties have a value. These values can be selected as fixed basic values or saved values from the previous session. To change a value, first tap on the property's field to enable the property. Upon activation, the field lights up in a preset bright color. At the bottom of the screen, a keypad for input of the same color lights up. The keypad can be chosen to be for absolu
