A metal member manufacturing method according to one form of this disclosure is a method of manufacturing a metal member that is thinner at some portions than at other portions. The method includes a formation step of pressing one surface of surfaces of a metal workpiece that are perpendicular to a thickness direction with a press-working die so as to form a raised portion in the other surface, and a cutting step of moving a cutting blade along the other surface to cut off the raised portion by shaving. In the formation step, the raised portion is formed such that the area of a cross-section of the raised portion that is parallel to a moving direction of the cutting blade and perpendicular to the other surface decreases toward an end of the raised portion on a rear side in the moving direction of the cutting blade.

A method for shaping a blind slot in a workpiece includes using a standard computer numerical controlled machine center to radially step a single slot broaching tool into a precursor slot in the workpiece for a predetermined distance to form a slot with a blind end. After the slot with the blind end is formed, the method includes rotating at least one of the workpiece and the single slot broaching tool and radially stepping the single slot broaching tool into another precursor slot for another predetermined distance to form another slot with another blind end in the workpiece. The another predetermined distance is the same as the predetermined distance, or in the alternative, the another predetermined distance is different than the predetermined distance.

A metal member manufacturing method according to one form of this disclosure is a method of manufacturing a metal member that is thinner at some portions than at other portions. The method includes: a formation step of pressing one surface of surfaces of a metal workpiece that are perpendicular to a thickness direction with a press-working die so as to form raised portions in the other surface; an application step of applying a lubricant; and a cutting step of moving a cutting blade along the other surface to cut off the raised portions by shaving. In the formation step, a sump in which the lubricant is held is formed between the raised portions in the other surface or at a position on a rear side of the raised portions in a moving direction of the cutting blade, and in the application step, the lubricant is applied to the sump.

Positions of both end edges of a weld bead in a bead width direction are measured over the entire circumference of a liner in a circumferential direction of the liner. Based on information on the position of the end edge, bead profile information being information on a shape of the end edge of the weld bead over the entire circumference of the liner in the circumferential direction is created. Based on this bead profile information, machining information of the liner per rotation of the liner being position information of a cutting tool in the bead width direction per phase in the circumferential direction of the liner is created so that a moving locus of the cutting tool relative to the liner along the circumferential direction of the liner approximates the shape of the end edge of the weld bead over the entire circumference of the liner in the circumferential direction.

A machine tool for performing a cutting process on a workpiece with a cutting tool, includes: a pre-machining shape acquisition unit configured to acquire the shape of the workpiece before cutting, as a pre-machining shape; a target shape acquisition unit configured to acquire a target shape of the workpiece after cutting; a differential shape acquisition unit configured to acquire a differential shape between the pre-machining shape and the target shape; and a machining path setting unit configured to set machining paths so as to perform the cutting process on the differential shape only.

A cold-weld burr removal system is disclosed according to various embodiments. The cold-weld burr removal system can include a clamping block having a clamping passage that extends along an alignment axis, and a removal block having a guide passage alignment axis centered about the alignment axis. The removal block can define a burr receiving chamber. The system also can include a cutting head insert having a cutting portion and a cutting passage. The cutting head insert can removably attach to the removal block and the cutting portion can protrude into the burr receiving chamber. The system can include a linear actuator that connects the clamping block to the removal block. The linear actuator can move the removal block in a direction along the alignment axis to increase a separation distance between the clamping block and the removal block when a linear actuation initiator initiates movement of the linear actuator.

Embodiments relate to methods and apparatuses that remove a frame from a solar module in order to facilitate its recycling. Such a deframer may feature one or more characteristics to promote its portability (e.g., to a site of former installation of the used module). Such characteristics can include but are not limited to: having certain components (e.g., moveable protection doors) formed from lighter-weight aluminum; and having retractable legs to enhance its compact size in a transport configuration (e.g., in a trailer or on the back of a truck). In some embodiments a module deframer may employ a cutting system to remove junction box(es) from a PV module. Such a cutting system may use a single cut motion that is adjustable.
