Title:
ELECTRONIC CAM CONTROL DEVICE AND ELECTRONIC CAM CURVE GENERATION METHOD
Document Type and Number:
WIPO Patent Application WO/2013/175615
Kind Code:
A1
Abstract:
An electronic cam control device is provided with an electronic cam curve generation unit which generates an electronic cam curve so as to pass through a plurality of designated coordinates that define a relationship between major axis positions and minor axis positions, and an output unit which outputs minor axis positions corresponding to the major axis positions as position instructions to an external device according to the electronic cam curve. The electronic cam curve generation unit generates an electronic cam curve in which a cam velocity waveform, in which the electronic cam curve has been differentiated with regard to the major axis positions, has intervals with a uniform cam velocity for each area that is between designated coordinates, and has monotonic acceleration/deceleration intervals connecting together intervals with a uniform cam velocity by accelerating or decelerating while monotonically increasing or monotonically decreasing between neighboring areas.
