The technological process route is also referred to as the production route, in other words, a work plan, a detailed structured description of activities within the technological process. A technological process route describes the sequence of actions necessary to produce a part, machine or device. The full description of the production route includes the individual…
Academic experience led to a return to the topic of developing a blank design as a casting. The selection of the casting mold division plane and the orientation of the casting, determination of the grade of allowance and accuracy class as well as the selection of foundry slopes are the main tasks of developing a…
As I wrote in the article Hadfield Steel, prison steel, milling, the aforementioned steel grade is difficult to machine. This is due to the specific austenitic properties of high manganese steels (Hadfield steels). These steels have very high tensile strength (from 350 to 900 MPa), which increases even to 2000 MPa (2 GPa). The increase…
By referring to the literature, we can search for a lot of information about milling as a machining method. This article addresses contemporary aspects of this type of machining. In addition to machining with conventional parameters (conventional and CNC machines) I referred to high-speed machining and machining of difficult-to-cut materials. Currently, milling works as an…

During his studies, then working at F.W.P. VIS S.A. basically, there was no documentation other than paper. The implementation of the CAD program was under way. Today, PLM and PDM systems (Product Lifecycle Management and Product Design Management) enable significant improvement in production management, including synthesis, flow, updating of technological documentation – as one of…

Workpiece – the object of work, which after the technological process has been completed, after all the provided treatments have been completed (change of shape, dimensions, surface and material properties) is the final product (part, machine or device). Workpieces are manufactured using various methods depending on the production volume. The blank is identified with the…

Previous post in the series: Technological process of sleeve, part 1. In the entry Sleeve – framework process – forging, a blank design is presented as forging. This project applies as part of the framework technological process discussed first, using conventional machine tools. The design of the blank as a forging can be developed as…

The standard of technological times (norm time) – determined at the end of the traditionally developed technological process. The general definition defines the standard of machining time as the amount of time necessary to carry out specific activities in given organizational and technical conditions, by a defined number of employees. Providing for [4] the norm of…
