StuderTechnology: Grinding technology, grinding times, unit cost calculation and simulation . the universal cylindrical grinding machine into a thread grinding machine . conventional programming, often with cycle time reductions of 50% or more.
variables of the problem of cycle time modelling and how they influence in the magnitude of the cycle time. This method is intended as a complement to the use of optimization applications that require the use of a nonnumerical, analytical and low computational time calculation model for determining this parameter. 2 Background Cycle time ...
In the grinding process, due to the elastic deformations of grinding machine and grinding wheel, the ground depth of cut is smaller than the applied depth of cut. Consequently, the ground depth of cut has to be controlled in sparkout grinding process. However, the cycle time in sparkout grinding process is not easy to be estimated. From such a viewpoint, in this study, using specific ...
Jun 01, 2010· Run at a spindle speed of about 1,800 rpm, the previous reamers took 3 to 4 seconds to finish a hole, whereas cut time for the new tool is seconds per bore while running at 4,385 rpm, a 453sfm cutting speed and a 157ipm feed rate.

Reduce the cycle time by a small amount to see the overall reduction in the production time. For example, if a single cavity mould is required to produce 20,000 parts with a 19 second cycle time then the number of hours required is However, if the cycle time is reduced to 18 seconds then the time is reduced to hour.

So at the ideal pneumatic cushioning point, not only is end shock minimized, but deceleration time is also reduced, which translates to shorter cycle times. A 20% to 40% reduction in total cycle time is not unusual when ideal cushioning is achieved. Effects of pressure variations. Figure 2. As shown, ideal cushioning occurs at bar for a given mass.
In order to realise the bore cylindricity, the stroke length and position of the honing tools must be adjusted such that with a standard work stroke approximately a third of the honing stone protrudes at the upper and lower ends of the bore (stroke length = bore length – 1/3 honing stone length). Honing is also possible with blind holes.

during the entire grinding cycle is used for analysis. The monitor of the grinder displays the spindle motor current during grinding and the maximum motor current value is recorded manually. Grinding cycle time is the time of actual grinding. It does not include the time for the wheel to approach the wafer surface and the sparkout time.
– the life time of the spindle can be extended. (One single replacement of a spindle costs more than a balancing machine) – the frequency of the downtime of the machines is decreased. The most expensive factor in a production is machine standstill – the result of the production is .
The Fanuc G75 grooving cycle has multiple parameters, which can be set according to your needs. In this post here is a cnc program example for the G75 Fanuc grooving cycle. Although it is a simple cnc program example for grooving, but this cnc program can be easily altered to your needs.
