rf1

% rf_cam.m %% This program determines the cam profile for a translating roller% follower.

% Variables for calculation % rb=base circle radius% r0=radius of cam follower roller or cylindrical face% d = follower offset% xc=x coordinate of cam point% yc=y coordinate of cam point% xf=x coordinate of follower center relative to cam% yf=y coordinate of follower center relative to cam% rise = maximum follower displacement% direction = direction of cam rotation [CW(-), CCW(+)]% ainc = cam rotation angle increment (deg)

% Graphics Variables

% h1=handle on the first axes in the window (cam animation)% h2=handle on the second axes in the window (displacement diagram)% h3=handle on the fourth axes in the window (pressure angle)% Displ=line representing the follower displacement% dbead=bead which follows the displacement throughout the animation% Pangle=line representing the pressure angle% pabead=bead which follows pressure angle throughout the animation% stem=line for follower stem% roller=line for follower roller% cam=line for cam% baset=line for top of slider guide% baseb=line for bottom of slider guide% pin=line for the cam axis% bush=line representing the cam bushing% xmin, xmax= x limits for the axes% ymin, ymax= y limits for the axes
