The analysis of the camshaft is a relatively simple process.

An interactive camshaft calculator where engine builders can see how valve overlap and boost efficiency is affected by a camshafts physical design. These cams typically have more exhaust duration to push more rumble into the exhaust system. Cam lobes are responsible for opening and closing of valves in an engine cylinder which are appeared on the camshaft.

Click to download the Demo version 2xx std. Camshaft lobes are designed by starting with the lift curve and working backwards to determine the lobe shape that will produce the lift curve. Program is intended for engines with flat or roller lifters.

For maximum power Lugging torque. Cam lobes modeling process using CAD software like Creo involves an integrated approach which is tedious. Kip Fabre - Cam Motion.

A CNC process controls a mounted follower that moves from lobe to lobe then journal to journal where it is lowered against the camshafts surface as it is rotated 360 degrees. How to use MGIs Camshaft Calculator When shopping for camshafts from different manufacturers enter each of their supplied cam card specs into MGIs Camshaft Calculator. Ones that I know.

The camshaft is defined by valve lift and duration which is further defined as opening and closing points. Click on the image for the presentations. The CNC control software translates the followers.

We can output profiles to suit CNC grinding on Landis and Toyoda CNC cam grinders as well as lift data for manual cam grinding machines using master plates. As we all know the purpose of a camshaft is to open and close a valve at a certain time. The XE cam profile is very aggressive and requires stiffer springs to control the low-lobe lift well.

We offer two basic packages for lobe designs. For this reason we need to learn a bit more about lift curves before we can discuss how lobes are designed. And the download link will be mailed to the email address you have used to order.

CONCLUSION OF CAST CAMSHAFTS. Version only demo. The latest in digital camshaft design testing equipment.

Adding the Lobe-Profile Library CD Dynomation6 and DynoSim6 users can model valve motion and engine output with unprecedented accuracy using the entire Comp Cam lineup. There are 12 months of free updates included. Mike Jones - Jones Cam Design.

Call today for your new billet cam Billet Turbo or custom work. Camshaft lobe designers. Carmakers are downsizing engines to boost fuel economy and to reduce CO 2 emissions.

Danny Crower - DCR. A full cam profile can be automatically generated for you based on the opening and closing points or lobe center angles and duration and lift heights that you specify or you can enter your own measured or existing data. I wonder if we could approach the issue of camshaft selection from a different approachcamshaft lobe design.

In this study the Modeling of cam lobes has been done to validate the idea of Design Automation. The cam is the XE270 218email protected and 512 lift. Fig4 Bucket tappet cams for valve lift Designs A-E.

Professional Cam and Perfect Cam is the ideal and complete software for engineering team tuner etc. Lobe lift sometimes called cam rise is the height of the eccentric portion of the cam lobe above the base circle. Camshaft Analysis Validation EZ-Cam Machine.

Context if the cam and cam tappet surfaces each have surface finishes of 025 micron and the lubrication film at its. An example would be if the rocker arm ratio were 15 to 1 the valve lift would be the cam lobe lift multiplied by 15 at any point. By hoffman900 Tue Nov 16 2021 658 pm.

Another trend impacting camshaft design is the move to smaller turbocharged engines. Cam4arc Program designs cam lobes with 4 circular arcs and can create both mild and very aggressive lobes. Billy Godbold - Comp Cams.

I havent been so impressed by camshaft as this one idle is very good idle torque is phenomenal but it will pull to 6k. This is a real problem for the grinder when checking the Jerk or 3rd derivative of the production cam as Jerk can get very large in all the wrong. The majority of my cam profile designs are for conventional valve trains.

Cam Lobe Design Software Get a custom camshaft for Your engine. The rocker arm transfers the motion of the valve lifter riding on the cam lobe to the valve and increases the lobe lift by the amount of the rocker ratio which is typically 15 to 171. This material is exceedingly scuff-resistant and is the only material for producing quantity OHC performance camshafts.

With the buyouts people passing people retiring curious as to who is left designing camshaft lobes. Not the same ole grind. We measure cylinder head valvetrain geometry and use modern software to output camshaft lobe profiles to give the designed valve lift curves.
