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 download.gif (909 bytes) 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. download.gif (909 bytes) D4CAM: 4 exponent polynomial curve fit program for flat or roller translating followers.

2. download.gif (909 bytes) 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. download.gif (909 bytes) 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.
