Truing operations deal with the form or profile of the grinding wheel. When truing a new abrasive wheel, the grinding face is altered to allow the abrasive product to do what it needs to do. Routine truing during the grinding process corrects the wheel profile and compensates for form loss as the wheel breaks down under regular use.

2.2 Mathematical model of flute-grinding for the taper end-mill. In 5-axis CNC grinding, the flute is generated by the helix motion between the grinding wheel and the end-mill. The flute-grinding processes can be divided into two steps: (1) grinding wheel set-up and (2) grinding wheel moves along a 5-axis helix. 2.2.1 Model of the grinding …

1 – Taper. Whether it is an I.D. or O.D. operation, taper is one of the most common problems in grinding and finding the cause can be tough. In some cases, it is as simple as adjusting the oscillation stroke to be longer or shorter to compensate. In others, dressing a reverse taper into the wheel may be the best way to handle things.

rotation of the sample between stages while the grinding angle must be held constant during the grinding at any on stage. Recall that "The sample MUST be washed thoroughly before proceeding from one grinding operation to the next"! Wet grinding is generally applied in medium and fine grinding to avoid possible side affects due to heating 1. 2.
