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.)

output screen shows how our programs give you an instant view of your
cam.
