Machining Tolerances

Allowances for Machining Bars

When regular quality alloy, special quality, or carbon hot rolled steel bars are to be machined, it is advised to make adequate allowances for surface finishing and specify the hot tolled or thermally treated sizes accordingly. Such allowances require consideration for the manufacturing practice utilized to remove the surface metal, as well as the bar size, length, straightness, size tolerance, and out-of-round tolerance. Bars should be straightened before machining.

Recommended Minimum Machining Allowance per Side, Percent of Specified Size

BarsNon-ResulfurizedResulfurized
Turned on Centers

3.0%

3.8%

Centerless Turned

2.6%

3.4%

Centerless Ground

2.6%

3.4%

 

(Based on bars within special straightness tolerance) Since straightness is a function of length, additional machining allowance may be required for turning on centers.

 

When regular quality alloy steel and special quality carbon steel hot rolled bars, such as squares and flats, are machined by methods other than shown in the table, the recommended minimum surface removal is 1.6% of the specified dimension for non-resulfurized steel. Sizes under ⅝" should be 0.010 of an inch for non-resulfurized steel, and 0.015 of an inch for resulfurized steel.

Resulfurized grades are categorized by a poorer surface. The increased surface removal shown above and in the table is recommended. Conversely, steels made to higher qualities may permit lesser amounts of surface removal depending on size, grade, and quality specified.

1115 and over 0.10 max, 0.10/0.20, or 0.15/0.30

 

Lead: When required, lead is specified as an added element to standard steel with a range of 0.15/0.35. Such steel is identified by inserting the letter "L" between the second and third numerals of the grade, i.e. 11L17.
