Turning Cut Calculator II 1.4.2

TURNING CUT CALCULATOR II is a mobile application tool for operators of turning lathes, CNC operators, CNC programmers etc. who work with processes in turning lathe machines. In an easy way, can all data be manipulated for a turning cut.

MAIN PROPERTIES

- Possible to choose 1 of 14 different languages at any time (machine translated)
- Calculates the time for a lathe cut by using given processing data
- Calculation of input data also gives values for surface finish, material removal, cutting forces, torque and power
- Possible process-data that can be changed are diameter, cutting length, cutting speed, spindle speed, feed rate per revolution, feed rate per minute, nose radius, surface fineness, turning type, cutting depth, entry angle, the 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 fineness from given nose radius and feed
- Calculates an approximate feed from given nose radius and surface quality
- Calculates material removal and rate from given data
- Calculates approximate cutting forces from given data
- Calculates approximate torque and power from given data
- All selectable values, except one, can be changed with the input of absolute value or with buttons for incremental change
- Required updates of affected values occur immediately
- Switching between change methods is made by a long tap on the row with the property to change
- Possibility to get a short explanation about a property with a fast double tap on the property's row
- Possibility to get explanations of other result values with a quick double-tap in the specific area shown
- Ability to select time for viewing highlighted text and active buttons
- Ability to select color theme for, among other things, highlights and active buttons
- Ability to adjust color tones for the color themes
- 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 property's value, first tap on the property's field to enable the property. Upon activation, the field lights up in a preset light 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 absolute or incremental input of values and is adapted to current property. Switching between the different keypads is done with a long tap on the property field.
In conjunction with activation of a property, in most cases, other property fields (subvalues) are also lit in a darker color to indicate that the value of these properties will also change.
With a quick double tap on a property's field a brief description and a descriptive image of current property can be obtained. The same thing happens when you double tap the result field on page 2, but all results are described in a scrollable image.

Page 1 is used for input and calculation of cutting data, surface fineness and cutting time. Page 1 manages itself and is not dependent on page 2.
Page 2, on the other hand, is dependent on page 1 and is used for further data entry to calculate material removal, cutting forces, torque and power.
