Calculating MRR In A Grinding Application
To work out the volume of one cut, work out the cone volume of before and after then subtract. But beware that as the part diameter decreases the volume removed per cut decreases. However assuming a grinding application, you probably aren't removing enough to worry about so I would take that as negligible.

The preceding work centre can only start making the products when it gets its request, so that queues and work in progress (WIP) are greatly eliminated. In contrast, an MRP-based 'push' system schedules the jobs in advance for a series of work centres, and each work centre pushes its completed jobs to the succeeding work centres.

4.2 Activity Based-Costing Method | Managerial Accounting
The primary difference between activity-based costing and the traditional allocation methods is the amount of detail; particularly, the number of activities used to assign overhead costs to products. Traditional allocation uses just one activity, such as machine-hours. Activity-based costing used four activities in this case.

What is Cylindrical Grinding - Steps in Cylindrical Grinding
In cylindrical grinding operation, the work is mounted between two centres and is rotated. A grinding wheel is mounted on a spindle and revolves at much higher r.p.m. than the work. The work centres are mounted on a table which can traverse at various feeds so that the entire length of the work passes to and fro in front of the wheel.

The ABCs Of Activities Based Costing | Modern Machine Shop
The essence of Activities Based Costing is linking activities to costs, then linking costs to jobs. Figure 1: The averaging inherent in flat-rate costing inevitably causes a shop to over- or under-quote about 20 percent of the jobs it bids on. These odds aren't good enough to keep today's job shop in the running, says Bill Starn.
