Research on Cam Contour Error of Grinding Machining,

August 2014; Applied Mechanics and Materials 620:199-204; DOI: 10.4028/www.scientific.net/AMM.620.199 Authors:How camshaft grinds go awry: – Moore Good Ink,Tellingly, a skilled cam-grinding eye and canny judgment are indispensible. To determine valve timing intake or exhaust or both can be advanced or retarded. Consequently, whatever the lobe separation, they have to be accommodated within the case-hardened rim. Before you run the cam, a Rockwell test would confirm surface hardness but not its depth . To achieve this, the conscientious grinder,Cam grinding to customer spec - Data requirements - Don,,27/11/2020· Re: Cam grinding to customer spec - Data requirements Post by Rob R » Fri Nov 27, 2020 1:42 am Mike will have to weigh in if this is his preference, but I'd recommend your sitting down with your best engine-car-guy friend and tell him exactly how you intend to operate the engine/vehicle and what is your budget for the entire project.

A methodology for contour error intelligent,

20/03/2012· Grinding is used to meet the accuracy and surface finish requirements of the cam profile in most applications. In order to eliminate the contour error and enhance the processing precision of cam grinding, a methodology for contour error precompensation in cam grinding based on case-based reasoning and rule-based reasoning was implemented. By comparingCamshaft grinding: Advanced technological innovation,,07/06/2016· This allows grinding engineers to accurately predict what’s happening in the grinding zone and avoid high grinding temperatures. Cam grinding, in contrast, is “nonround grinding.” Here, the workpiece rotates and the wheel feeds in, but the wheel-spindle assembly also simultaneously oscillates back and forth to produce the strange “egg shape” of the cam.How to grind cam followers - YouTube,11/12/2012· Grinding camshaft followers on an inline 6 John Deere 4430 turbo diesel

Using the Sherline CNC Cam Grinder

The Sherline cam grinder was designed to be affordable and accurate. We have assumed that the user has some knowledge of g-code, CNC and how to square up or “tram in” a machine so all axes are properly aligned. The machine is carefully pre-aligned at the factory, but rough handling in shipping could knock something out of alignment. As with any new machine tool, it is theCam Grind - Vintage Ford Forum,15/12/2020· cam grinder. by old victoria. got the cam back for the model A drag car .Jim Brierley ground me his M28 race grind, you need a cam he is the man!!!

Where I come from the name EdResearch on Cam Contour Error of Grinding Machining,,The cam is machined in the way of X-C biaxial linkage motions. The linear motor drives the grinding wheel mechanism to get the motion of X axis, and the motion of C axis is the rotating of cam driven by the torque motor. Because of the servo-system-lag of the two axes, the cam contour error is formed in the X-C biaxial linkage motions. Moreover, the following position

Error in end point of circle while grinding cam - Entries,

In autocad i rotate the cam shape at 1 degree intervals, and get the position of the grinding wheel (which moves only on the x axis) at tangent points then draw the c-v axis profile (you can find in the attachment), later from this profile i get delta c and delta v values (i work incremental) and get arc radius values and write the code below,Research on Error Sources Caused by Servo Feed in,In order to illustrate the effect of servo lag upon cam Contour error, X-C servo axis Trajectory coordinates have been acquired in real-time with dual-channel mode during cam grinding. By comparing the Trajectory coordinates detected and the interpolation contour, the errors caused by servo feed lags were verified, and the mechanism that how axis feed acceleration impact onA methodology for contour error intelligent,,Grinding is used to meet the accuracy and surface finish requirements of the cam profile in most applications. In order to eliminate the contour error and enhance the,

The Cam Contour Control in Grinding Based on Repetitive,

01/01/2015· 2. CAM CONTOUR ERROR 2.1 Cam Profile Error Sources In the cam grinding process, error sources that can affect the contour accuracy mainly including wheel size error, wheel topography error, wheel positioning error, and the dynamic model of nonlinear factors and inaccurate (Zhang XH et al., 2013). It is well known that a blunt grinding wheel increases theA methodology for contour error intelligent,,In CNC cam grinding, the contour error will inevitably exceed the regular range when two axes have different lag caused by the high-speed grinding regardless of theIrregular shape cam grinding - Industrial/Mfg,By keeping the two cams (the regular one and the 10x bigger one) in perfect sync via a timing belt and pulleys, and by rotating them while gradually and precisely bringing the grinding wheel down against the cam, we can grind away the required shape, until we're left with only a thin line of paint on the cam. The beauty of the principle is that this way we're not depending on the room,

through the cam grinding X, C-axis error analysis [14,15], applied to the eccentric shaft grinding analysis, through the simulation of X, C axis error curve. Assuming that only the X axis produces...Method and apparatus for grinding cam with re-entrant,,Thus, the cam of the workpiece can be efficiently ground with the taper section of the grinding wheel in the plunge grinding, and then, the cam can be ground with the spherical section of the grinding wheel in the traverse grinding without involving an error in cam profile due to the difference in the grinding wheel diameter. Accordingly, it can be realized to grind the camHow can I make my own Cam Grinder? - Practical Machinist,22/06/2007· But if you still want to make a cam grinder - I'll set you up with a controller that is unmatched in profiling using Hermite B-Splines. 04-01-2006, 12:07 AM #8. kenh.

In comparison with the current cam grinding strategy, analysis results derived from the modelling of the process indicate that it is applicable to keep the grindingMaking the cam - Prof Blair & Associates Home Page,The cam profile and the cam tappet interface are normally produced by grinding the surfaces. Typically, a simple grinding operation will produce the surface finish that is measured at 0.25 micron as a centre-line-average (CLA). This is the average height of the asperities on the surface. If the surface is first
