Task:
At a
a) Involute and gear testing machine
b) Roller testing machine
gears and crankshafts must be measured and evaluated with the aid of a computer. The measured values determined in this way must be visualized in the form of a diagram on a screen or printer.
The evaluated measurement data should be retained for quarterly evaluation and for statistics and then stored on a data carrier for archiving. Individual measured values must be retained for two days before they are deleted. The resulting target values of the respective test specimen must be stored in a test plan.
They must be evaluated:
a) Flank shape and flank direction
- Shape deviation
- Angular deviation
- Total deviation
b) Crankcase line (only on the crankshaft)
- Deviation of straightness
c) Rolling test
- Rolling jump
- Rolling deviation
- Axial runout
Solution:
A computer with an analog-digital card was used to record the measured values.
All measurements are semi-automatic.
The start signal for measuring is given by the measuring machine.
Once the measurement has been completed, the measurement diagram is displayed on the screen for visual inspection.
The target values specified in the test plan, the calculated actual values and the delta values of the actual values to the target values are written under the measurement diagram.
The same edge shape and edge direction are displayed on the screen as on the printout.
