Toothpaste testing in a brushing simulator
A demonstration of toothpaste testing in a tooth brushing simulator.
Test configurations
Positioning (X Auto)
This test configuration allows precise and automated control of the horizontal position (X direction) of a sample or sample holder. The control is performed through the Mach-1 Motion software (same as for the vertical stage Z) where all displacement functions and the building of displacement sequences are possible. The addition of a horizontal positioning stage can be used, for example, to automatically position the sample at another location under the vertical axis or to apply a sinusoidal displacement (simulated brushing). Different travel ranges are available for the horizontal stages (either 50, 100, 150, 200 or 250 mm) and two displacement resolutions are available (either 100 or 500 nm).

How does the Scan function works?
This function moves the X and Y horizontal stages (or Theta torsion stage) to the next position on a predefined positions list. Contrary to the other functions, this function is directly linked to the repetition number of the sequence (see Repetitions in the Sequence section). For example, in order to displace the stages to every position included on the list, the number of repetition of the sequence should correspond to the position number on the list (calculated in the “# Position” field). When the sequence is executed, the Scan function will move the stage to the first position on the list. At the second repetition of the sequence, the function will move the stages to the second position, and so on. When the number of repetitions of a sequence exceeds the number of positions on the list, the function will reuse the same set of positions in loop. For example, if a positions list contains 5 positions and the sequence is repeated 10 times, the 5 positions will be visited twice. To minimize the risk of damage to the load cell, before each repetition of the Scan function, the Z-axis stage will first be repositioned to the position it was at the first Scan of the sequence.
Parameters:
POSITIONS X-Y (UNITS) - List containing the X and Y (or Theta) coordinates of predefined positions.
LOAD X-Y - Loads the X and Y (or Theta) coordinates from a file (tab-delimited text file). When prompted, choose the file that only contains the coordinates to be added to the list.
PASTE X-Y - Pastes the X and Y (or Theta) coordinates from the clipboard into the table.
CLEAR XY - Clears all the X and Y (or Theta) coordinates in the table.
