Formulating CAM parameters for surface patterning by ...
Grinding employs an abrasive product, usually a rotating wheel, which is brought into controlled contact with a workpiece surface. The grinding patterning process can be simulated using computer programming with specific user-defined parameters. To predict the surface pattern that will result from grinding with the grooved wheel, calculating the CAM parameters is …

Art Reitsma's Cam Grinding FAQ - math.uwaterloo.ca
After grinding, all camshafts must be "Parkerised(tm)". This process puts a coating on the lobes to hold the oil during initial break-in. If this is not done, the oil will not stick to the cam, greatly accelerating wear during the first few hours.
Cam Relief Grinding - Cam Relief | Tri Star Engineering
Cam relief grinding, however, overcomes the shortcomings of conventional cutter techniques, particularly in cutting tools with complex form geometry. The technique of Cam Relief grinding removes less material from the tool in the grinding …

Cam and Shape Grinding - Page 2 - Practical Machinist. The cam grinding process involves one pass across each of the lobes in high gear, with the wheel winding in at a preset speed to the desired base circle size, then a preset time delay with the wheel remaining in its final position against the lobe to allow the wheel to 'spark out'.
Cam-grinding options | Cutting Tool Engineering
Last year, I was involved in a fascinating project to optimize cam grinding for a major European truck manufacturer. Instead of using the constant …
In-House Camshaft Grinding - Texas Speed
In-house cam grinding allows for stricter processes that alleviates issues such as cam peeling from burning during grinding, "whistling" while the engine is running due to improper lobe finish, higher efficiency in the cam grinding time and process, better quality control, and the most state-of-the-art camshaft grinders in the industry to ...
A Model Camshaft Grinding Process | Modern Machine Shop
The master cam roller is then aligned to the next master cam. Wheel wear from cam to cam is avoided by turning the work table slightly. To learn more about cam grinding or other types of precision grinding machines, call Maximum Advantage-Carolinas. Our Fort Mill, SC office serves clients worldwide by providing the very best grinding equipment ...
The Camshaft Reconditioning Process - Highway and …
Regrinding is always a part of the remanufacturing process. If the wear on a camshaft is minimal, the rebuilder may only have to regrind the cam to finish remanufacturing it. A remanufacturer will use a CNC grinder to grind down the lobes of the camshaft to ensure they provide the proper lift that is required for the engine. There are two basic ...
Formulating CAM parameters for surface patterning by ...
With the intention of extracting CAM parameters, a mathematical model is developed for a grinding patterning process, starting from the unit pattern geometry of the workpiece plate.

Investigations into cam grinding process: Zhang, Xiaohong ...
In this book, our aim is to achieve low cost, high quality and intelligent manufacturing for cam grinding. Part 1 is to study a novel grinding strategy for …
Research on cam grinding process used on-line variable ...
The cam grinding experiment results that the grinding forces stability used fuzzy on-line velocity is better than constant speed grinding. Discover the world's research 20+ million members
Engine Cam Grinding - machsupport.com
Engine Cam Grinding. I was looking for thoughts on a concept of a cnc cam grinder. The purpose would be for small engines but the concept would be universal to cam grinding. I would like to make a two axis machine. One axis would be a rotary the other would be Y (I think) that would move in and out on a plane parallel to the base of the grinder.
Chatter detection in camshaft high-speed grinding process ...
The grinding process system is stable when the grinding depth a p = 10 μm, ... and the chatter frequency of different contour sections of cam is not consistent under the same process parameters. Furthermore, the lift curve section is the most likely to occur chatter. (3)
Evolution of Performance Camshaft Grinding, Finishing ...
Evolution of Performance Camshaft Grinding, Finishing. Comp Cams has made numerous improvements to its CNC camshaft grinding process. The company has also implemented what it calls its "Micro Surface Enhancement" finishing technology, which works in tandem with its enhanced grinding process to further improve camshaft longevity and durability.
OD CNC Grinding: The "Non-Round" Way - Okuma
The GC-34NH CNC Cam Grinder can grind a variety of "non-round" shapes on the OD of a part, such as ovals, flats, triangles, and even squares. A Common Non-Round Challenge: Changeover Time. For all of you motorheads and race fans, let's take a look at the example of an aftermarket camshaft. A common challenge facing aftermarket camshaft ...
Cam Re-grinding - Page 2 - Don Terrill's Speed-Talk
Re: Cam Re-grinding. I still haven't finalized the build plan as I still haven't disassembled the old engine to determine it's viability. I'd wanted to build a forged shortblock bullet to go with the top end. But now that half the top end is smoked (heads are good to go still), I can't say what's next until I measure the old block.
Research on constant grinding depth model for cam …
In order to mitigate the problems in CNC grinding of a camshaft caused by varying grinding depth along the periphery of the cam, a novel grinding strategy is proposed to keep the grinding depth constant during the process. In comparison with the current cam grinding strategy, analysis results derived from the modelling of the process indicate that it is applicable to keep …
Simulation of cam grinding mechanism with CNC camshaft ...
Then, cam grinding process with CNC camshaft grinder is analyzed theoretically, and horizontal travel speed setting of wheel head correspond to the rotation speed of a workpiece is made clear in this study. Furthermore, simulation analysis method is developed, and proposed unique 3 grinding techniques to control the rotation speed of a ...
