Tool making: automatically create dimensioned engineering drawings

Tool manufacturers can now automatically create dimensioned engineering drawings of machine tools showing their precise geometry, by using a new facility for NUM’s renowned Numroto grinding software. By producing cross-sectional views of a tool – at any position along its length – the new Numroto Draw function can effectively automate production verification. The drawings can also incorporate images obtained directly from 3D simulation of a tool, enabling even complex grinding details to be portrayed graphically and unequivocally.

Numroto Draw produces fully dimensioned engineering drawings of machine tools, including accurate portrayal of the tool’s profile and cross-sectional geometry.

Numroto Draw is ideal for tool manufacturers seeking a means of showing customers precise details of tools prior to production, or of confirming the ground geometry of a tool as part of the delivery process. The software is also likely to prove popular with tool resharpening companies, as it enables them to provide customers with documented confirmation of work, either before or after it has been carried out.

One single source
The drawing is derived directly from the same data source as the CNC program, ensuring there is no ambiguity in the process. Using data that defines the spatial course of the tool’s cutting edge, the software automatically calculates all dimensions that require presentation and then generates the appropriate drawing. If any of the dimensions do not meet a customer’s requirement, they can be amended very easily.

Tailored solution
The drawings created by Numroto Draw are fully editable. Header information can be structured by the user to suit the customer’s requirements, and the tool designation can be taken directly from the Numroto database. A separate table, showing the main parameters of the tool, can either be created by the user or adapted from one of the templates supplied by NUM, and again can be populated using values from the Numroto database to help save time. The documentation – which can be structured to occupy several pages if desired – can also include a graphical representation of the grinding wheel pack, together with a table containing information about each wheel, such as its diameter, width and grinding angle.

Coincident with the launch of Numroto Draw, NUM has also further enhanced the capabilities of Numroto in a number of key areas.
