A knife assembly for cutting a substrate during relative motion between the knife and the substrate, the assembly including a knife having a distal knife blade and a proximal knife shaft attached to a holder rotatable about a first axis perpendicular to the substrate to define a cut direction angle. The holder is also configured to rotate the knife blade about a second axis perpendicular to the first axis to form a notch angle relative to the first axis. The notch angle is preferably automatically infinitely adjustable within a range of angles. The holder may also, optionally, be configured to rotate the knife blade about a third axis perpendicular to a plane defined by the knife blade to adjust an angle of attack of the knife blade relative to the substrate.

A drilling machine and a drilling method including drilling a first bore in a material with a drilling machine by applying a torque to a drilling tool for imparting a rotation at a first rotational speed to the drilling tool, and applying a thrust to the drilling tool for advancing the drilling tool at a first feed speed into the material, wherein a drilling parameter is measured while drilling the first bore, and a second rotational speed and a second feed speed are determined based on the drilling parameter, then drilling a second bore at the second rotational speed and at the second feed speed.

A robot control system according to an embodiment is a control system for a robot comprising an arm, the arm being capable of holding a tool while rotating the tool and capable of moving the tool in at least two-dimensional directions, the arm being equipped with a rotating mechanism provided for the tool. The robot control system comprises a load-acquiring unit and a control-signal-generating unit. The load-acquiring unit is configured to acquire a force measured by a force sensor configured to measure a force applied from the tool to the arm during profile copying performed on a machining object by moving the arm while a copying guide attached to the arm and a copying mold placed on the machining object are kept in contact with each other. The control-signal-generating unit is configured to automatically control the arm by generating a control signal for the arm in accordance with the force acquired by the load-acquiring unit and with control information for the arm regarding the profile copying, and by outputting the control signal to the arm.
