The invention relates to the technical field of steering knuckle manufacturing, in particular to a flexible blanking process for steering knuckle forging round steel. The flexible blanking process comprises the following steps: firstly, measuring mass of a steering knuckle finished product as M, calculating mass N of a needed round steel rod according to a theoretical value of a forging material utilization rate, and calculating volume V of the needed round steel rod according to density of the round steel rod; then, blanking by use of a saw, measuring diameters of a plurality of positions of the round steel in a length direction along with forward movement of the round steel during blanking; calculating to obtain length when the mass of the rod is N; and blanking according to a length which is 100.8%-102% of the length. According to the flexible blanking process, the problems that blanking is carried out according to fixed length , and defective products are generated as a result of shortage of part of rod raw materials due to fluctuation of diameters of the round steel in the prior art are avoided. Flexible blanking is carried out according to diameter changes of the round steel, so that adverse effect caused by fluctuation of round steel diameters is reduced, and therefore, less machining allowance can be reserved, material waste is reduced, a material utilization rate is increased, and follow-up processing workload is reduced.
