Cam Design Programs
Andrews Products have a variety of cam lobe design software
programs to help you design cams to your exact requirements. Look for the  symbol that indicates which programs are currently available for
download. Just follow the links to download.
TIME-SAVING SPEED
 Typical
recalc/screen refresh time - 2 seconds.
Graphical
output to laser jet printer with one key stroke.
Stress
analysis available with D4CAM, D5CAM and SMOOTH4.
Evaluating
entire cam designs in real time quickly yields best possible cams.
TRUE CAD/CAM PERFORMANCE
All
programs run on any DOS based 386/486, Pentium PC.
VGA
color graphic output; 2 second screen redraw.
Toggle
between motion curves or cam shape graphic with one key stroke.
All
programs generate complete manufacturing data files in various forms. (Includes Landis
files).
INTERACTIVE, SINGLE SCREEN DESIGN CAPABILITY
On
screen editing of opening, closing events, and both ramps.
Save
all finished input design data to a disc file for retrieval later.
Change
all input parameters with mouse and keyboard (or tab key).
All
programs operate with inch or metric units.
ELEVEN DIFFERENT PROGRAMS
Each Andrews Products program has a specific application as outlined below. All
programs show graphical displays of lift, velocity, acceleration, jerk and cam shape. In
addition, there are screen summaries of max./min. values for velocity, acceleration, jerk,
radius of curvature and pressure angle.
1. D4CAM: 4
exponent polynomial curve fit program for flat or roller translating followers.
2. D47CAM: 4
exponent polynomial plus circular arcs for roller followers (No negative Rad curve).
3. CV4CAM: 4 exponent polynomial with a velocity limit for
flat followers with smaller dia. lifters.
4. D5CAM: 5 exponent polynomial curve fit program for
translating flat or roller followers.
5. D57CAM: 5 exponent version of D47CAM. (Eliminates
negative Rc for roller followers).
6. CV5CAM: 5 exponent version of CV4CAM. (Flat followers with
maximum velocity limit).
7. SWINGD4: 4
exponent polynomial curve fit program for oscillating arm follower systems.
8. SWINGD5: 5 exponent polynomial curve fit program for
oscillating arm follower systems.
9. SMOOTH4: Smoothing program for lift data - translating
follower systems.
10. SMOOTH5: Smoothing program for oscillating arm follower
systems: Imports valve lift and smoothes original valve lift data, if desired. Lift data
is then transformed into an oscillating arm cam design as measured by a translating
follower. Output files include all data suitable for cam manufacture and inspection.
11. CAM4ARC: Design program calculates complete 4 arc cam
designs (both sides and ramps). In addition to radius values for nose, flank, ramp, and
base circle, program needs values for event length, max cam lift, and follower type (flat
of roller). Flank and ramp radii can be different for open and close sides. All cam data
and arc transition points are calculated and presented as a graphical output. (For very
high lift short duration cams.)
This sample output screen shows how our programs give you an
instant view of your cam. |
