Abstract
A cam profile data creation apparatus sets cam profile data in which a phase of a drive shaft is associated with a displacement (set displacement) of a driven shaft, a rotation speed of the drive shaft, and an allowable error for the displacement of the driven shaft. A displacement (predictive displacement) of the driven shaft when the drive shaft rotates at the set rotation speed is found based on the set cam profile data, the set displacement and the predictive displacement are displayed to be comparable, and further a form of the display is changed depending on whether an error between the set displacement and the predictive displacement falls within the range of the allowable error.
Claims5
A cam profile data creation apparatus comprising:
- a cam profile data setting unit that sets cam profile data in which a phase of a drive shaft is associated with a set displacement as displacement of a driven shaft;
- a drive shaft rotation speed setting unit that sets a rotation speed of the drive shaft;
- an allowable error setting unit that sets an allowable error for a displacement of the driven shaft;
- a driven shaft displacement prediction unit that finds a predictive displacement as displacement of the driven shaft when the drive shaft rotates at the rotation speed based on the cam profile data;
- and
- a display unit that displays the set displacement and the predictive displacement in a manner such that they can be compared with each other and changes a form of the display depending on whether an error between the set displacement and the predictive displacement falls within the range of the allowable error.
