Apparatus and methods for providing a surgical table base with sufficient stiffness and adjustable support members with force feedback are described herein. In some embodiments, a base for a surgical table includes a base body to which other components of a surgical table can be coupled. A surgical table, and optionally a patient supportable by the surgical table, and any equipment to be carried by the surgical table, collectively representing a table load to be carried by the base body to support the surgical table on a surface. The base further includes a support assembly coupled to the base body to support the base body on the surface. The support assembly includes at least four support members. Each support member has a surface-engaging end and can transmit a portion of a total load represented by the weight of the base and the table load through the surface-engaging end to the surface. The surface-engaging ends of any three of the four support members define a plane. One of the support members is adjustable to move the one support member relative to a plane defined by the three of the other support members and thereby to change the portion of the total load carried by one of the support members. The base further includes a load sensor operably coupled to the support assembly and disposed to detect the portion of the total load carried by one of the support members.

To dynamically change the acceleration without trial executions of a machining program, a numerical control device, which controls a motor on the basis of a machining program that specifies a path for a drive target of the motor, includes a changing unit that changes the acceleration of the motor under the control of the motor on the basis of the inertia ratio, the acceleration-deceleration factor that can be externally input, or the current value of the motor.
